P: Scrolling over folders in library module doesn't work

Hi everybody,

I experienced a bug in LR scrolling behaviour within the library module. To describe the problem best, I recorded a screencast video with audio comment that I uploaded to my webserver:
http://www.silentcreek.de/lrbug/demo.avi
In short: Scrolling with the mousewheel over folders in LR's library module doesn't work properly.

Here is what I know:
1) The bug doesn't always occur. Sometimes scrolling works for a couple of days, but most times it doesn't, which is annoying, of course.
2) I could only reproduce this bug as shown in my demo video in the library module when trying to scroll with my mousewheel over the folders or publishing services. Everywhere else, it works fine.
3)The bug seems hardware independent: I experienced it on my laptop as well as my desktop (one Win 7 32bit, one Win 7 64bit; two different mice, one by MS one by Cherry).
4) I experienced this bug for quite a while with different versions of LR (currently 3.5, but the earliest version I used was 3.2)

I hope this helps to figure out the problem.

Thanks,

Timo

    Well, I already tried to track down the issue in Windows safe mode. That means that no 3rd party was started during the boot process and only the essential services were started. The issue was not resolved.
    What you forget to mention for your method, btw, is that you can run into serious issues when you disable essential system services. I will give safe mode another try though and see which services are actually started there. I'm very skeptical though.

    You can still use my general method to determine where the problem lies on your system... but it is fairly time consuming:

    1) Start by disabling all the startup items using msconfig
    2) If that fixes the problem, enable half of them and try again
    3) Keep doing this with half of the half, etc. until you find the culprit
    4) If it doesn't fix the problem, disable half of the Services and try again
    5) Use the same binary search method to find the problem Service

    Of course, this took me about 3 hours, because you have to reboot after each change. Fortunately, my OS is on an SSD so reboot is fairly quick.

    Sorry, but I CANNOT confirm this fix. I tried it but it doesn't fix the issue on my machine. Tablet PC Input services were already set to "Manual Startup". I changed it to "Disabled", restarted my computer and could still reproduce the bug in Lightroom. I even went so far as to completly remove the Tablet PC Input services from my computer (via "Control Panel", "Programs", "Turn Windows Features On and Off"), but the issue was not resolved.

    I spent several hours on this bug and finally fixed it on my system as follows:

    1) Start msconfig
    2) Change to Selective Startup
    3) Disable PC Tablet Services

    Now works properly, with all other services running and all startup items loaded as well.

    Note: I read on one web site that Silverlight might need PC Tablet Services to use Photosynth. I checked and I have Silverlight installed. Hope this helps.

    Thanks Viktor, haven't tried safe mode before. But I just tried it, and the bug occurs even there.

    @Lee Jay: Thanks as well. Could you please also post your system details (hardware, software that's running in the background) here?

    I can confirm this bug, exactly as described by Viktor, on Windows 7 64.

    Oh, I thought about running Windows in safe, have you tried it already?

    Will post my config tomorrow, doesn't have it right now. The system is Windows 7 64bit, and LR's version is 3.5.

    Interesting observation, Viktor.

    I just checked that, and it's the same for me. Didn't notice that before, but you're right: In Loupe mode it works, but in Grid mode it won't.

    In the meantime, I also found another user with the same problem on another (German) forum. I'm trying to get his system details for a comparison.

    Viktor, could you post your system details, please? Even though I already tried different mice, etc., just let me know what kind of setup you have and possibly, what applications are running in the background. Thanks.
