Strange auto-scrolling behavior in timeline

I'm having the same problem with the autoscroll in the latest update of CC2015 as well.  A support technician told me that Adobe is already aware of this bug and their engineering team is working on a fix.

The easiest, temporary work around for me is to close the sequence's timeline and reopen. I was noticing it happening when dragging effects from left monitor to right monitor timeline.

This bug has been happening since mid 2014 on a 2 monitor setup.  It was not fixed in the 2015 release.  Its a problem, and I blame Adobe for not fixing it since it is a serious impediment to workflow.  Judging by the posts on many forums, this is a big issue.  The  simplest fix I have found, is to close the timeline window, then re-open it, and work until the bug starts up again.  Rinse and Repeat as they say, and keep coughing up the $49 bucks a month because there is nothing better out there.

Enjoy.

I have managed to reproduce this issue internally and we have a bug logged against it. It's very difficult (for me) to get into this state, and I haven't found exactly what triggers it, but with enough repeated steps I'm able to cause it.

Here are what my findings have been:

1. Requires two or more monitors on a Mac OS X 10.10.3 or 10.10.4 system.
2. Requires having some floating panels, e.g. Project Panel/bins in the workspace, with other panels docked, e.g. Timeline.
3. Requires changing focus from floating panel to docked panel.
4. Requires performing a mouse edit (or general mouse activity) in the Timeline immediately after changing focus to docked panel.
5. Requires moving mouse cursor while button is depressed to specific regions of Timeline panel until view scrolls, then releasing mouse.

Sounds generic, but in real-world practice, I'm:

• dragging a clip from a bin
• dropping in a sequence, with the Timeline somewhat zoomed in
• drag-editing the head of the clip until the view scrolls left
• releasing the mouse button when the cursor is somewhere over the Timeline headers

I've also been able to reproduce the crash that others have mentioned, which is also logged.

If anyone can give me specific steps, and especially a screen recording, of how you get into this state it would be appreciated. I don't need to see that it *happens*... I already know it does and have reproduced that myself. However, I believe there to be a number of various ways that we can get into this state, and I want to see that once we have a fix, it's fixed for them all. Thank you for your help!

Same issue here on mac pro mid 2010 with 32gb of ram and running Yosemite. Running updated Premiere 2015, never tested on 2015 because I updated the OS and premiere on the same day.  

Adding to the voices. This is an issue for us as well. Two monitor setup on the latest Yosemite. Looking forward to a fix soon! Thanks Adobe

Great, thank you for the additional information, guys. So, when you're dragging into the Timeline, are you holding the mouse at one end or the other of the Timeline panel so that it scrolls (which is expected behavior when you're dragging with the mouse button depressed), or are you dropping a clip/effect into the current view, and then the scrolling starts following your mouse?

xmanpost: is your workspace layout similar to that posted by yellowdogdesigns? A screenshot would be great, if you can.

And thanks again for sticking with me on this--I know it's a frustrating issue but your assistance here will be instrumental in correcting this behavior.

Open call to everyone experiencing this issue...

I've tried reproducing this in-house for quite awhile and have so far been unable to come up with the combination of factors that leads to this autoscrolling behavior. I'm working with a late 2013 Mac Pro with a dual monitor setup, 10.10.3, and both Premiere Pro CC 2014 and 2015. No matter how I drag, trim, scroll and any other mouse action, I can't get this behavior to occur. That's not saying this doesn't happen--I've seen the videos that some have posted and I believe it is happening! But, as James has said earlier in this thread, this isn't happening internally and it's not happening for everyone, so if we can't recreate the situation we can't fix it. That means we need your help in reproducing this issue.

My thinking is that it's something related to how a workspace is set up, and how you interact with that workspace. Throughout this thread and others, there doesn't seem to be one particular action that causes the scrolling--for some it happens while dragging clips to and fro in the Timeline panel, while I've seen others report that it happens when dragging from the Project Panel or Effects Panel to the Timeline. That suggests to me that there is some sort of "hot zone" that when a mouse pointer is dragged across it, cause the application to act like the mouse button remains depressed even when it isn't. But it's that location of the hot zone that is a mystery. Bear in mind, this is just a theory, but if you're encountering this issue randomly, with this in mind you can mentally track what you were doing and where in Premiere Pro when this started occurring.

That all said, if you have a solid 100% reproducible situation, please let me know via PM. I'd love to get a project file from you (no media necessary) containing your workspace that can help isolate the issue. I'll need specifics on what you're doing when the scrolling starts. Thanks in advance for your help.

ok it happened with the wacom pen today so ill take that back. it was working fine till i dragged over from the bin to the timeline. i was adding reverb to an audio track.

I have a logitech M570 trackball. However, when I am just using my Macbook Pro (single screen), the M570 does not cause the autoscroll. Normally, once you go beyond a certain region it will start the scroll regardless of the window that is active. I've attached an image of where the scrolling would begin if you moved left of the area highlighted. I will test tonight with my second screen, as I am not at the location where my second screen is.
