P: Double arrow cursor over panels

OK. It seems that the good ol' Adobe rule also applies for this issue : once a bug survived one or two years, it becomes a feature. This will be never fixed.

> It seems the cursor (which probably comes from the panel resizer at the right
> edge of that panel) is only changed back to default in a very tiny area between
> the resizer and the folders list, but not on the folders list control itself.

Which certainly means that the mouse events don't propagate to the child windows of the main panel window. Probably a window style not correctly set.

When moving the mouse cursor swiftly from the image view over to the folders panel in the library module, the mouse cursor will almost always have the shape of a horizontal resize arrow pointing left and right. It will remain like this as long as the cursor does not leave the folders panel. It may only change again when the cursor leaves that panel and you try again. Sometimes it takes multiple tries to get a mouse cursor of the default pointer shape that you can actually work with. It's hard to point the resize cursor on a specific item and not miss it.

This issue has been there for a long time. Not sure whether it's already been in version 4, but it definitely is in any of the 6.x until today. I've seen other reports of this bug closed as fixed here, so I just try again, with a suggested solution.

As I guess the Adobe developers are not in control over their development tools, may I suggest handling the MouseEnter as well as the MouseMove events on that list control to update the cursor to a default pointer. It seems the cursor (which probably comes from the panel resizer at the right edge of that panel) is only changed back to default in a very tiny area between the resizer and the folders list, but not on the folders list control itself. You may not have noticed yet, but when moving the mouse from one point to another with sufficient speed, it will not be placed in every single pixel along that line, but it will skip pixels. If it skips the area that could properly update the cursor, then the cursor is not updated. When moving the cursoer very slowly, the issue does not occur. This is a fairly basic mistake that any trainee could make, but not very often. From my experience, I'm not expecting any greater level of experience from you, dear Adobe developers, so please use my explanation to fix that nasty bug, finally.

Yep.
And still just as irritating...

Edit to add: wow - five years old!  Really?!

Still not fixed after all these years. I can't believe it. Programming the mouse is one of the first things you learn when developing for Windows.

Not fixed!
Cursor is a 'Double-arrow' when crossing fast onto Folder Panel.
It occurs randomly when moving mouse cursor from grid to Folder panel.
It occurs more frequently when mouse movement is fast.
It does not occur when I move the mouse very slowly across the panel border.
Cursor defaults back to 'pointer' and stays if it moves over the desktop and back onto the Lightroom folder panel.

Hi,

Very old problem. Never fixed and probably will never be. I use to name such bugs "perpetual bugs". They have been reported multiple times since years, Adobe never cared, and now they belong to history. Without them, Lightroom would no longer be Lightroom. One of these days, they will be called features.

Forgive me if I don't use the right terms when explaining my problem.
Here is my scenario. When I am in the Library in Lightroom, for example, I have a number of pictures displayed in the middle of my screen. I have my keywords section in the right panel expanded so that I can click a picture to highlight it and then move my mouse to the right to click off the keywords in the list to add them. As I move the mouse right and left over the dividing line between the library and the right panel, the mouse doesn't change to the "single" arrow, rather it stays an arrow that points left and right. This is the arrow that it changes to when you want to drag that dividing line to make the panel wider or narrow. I can have my pointer as a single arrow and then click to select a picture and then move my mouse right very fast to the keyword area and as soon as it crosses that dividing line, it becomes this double sided arrow pointer. If I move the mouse right and left extremely fast, then most of the time it will be a single arrow when I mouse over the keywords. But I shouldn't have to move the mouse that fast in order to have a proper looking arrow. By the way, I can still click to add the keywords with this double sided arrow. Even as I move up and down over the keywords to select different keywords, the arrow won't change back to a single arrow until I move back over the pictures to select a new picture. Then it is a single arrow until I move back over to the keywords. I would like to point out that this has been the behavior since since I started using v5 with Win7. I have reinstalled and started from scratch a few times and now that I have Win10 and a clean install and new database using the Creative Cloud, I still see it. I hope I explained the issue so that you understand what I am seeing. I also hope that you can resolve this issue soon. Thanks.

It only happens if you move your mouse fast ( though normal use , I think)
If you move the mouse slowly ( not normal use) it does not happen.
So let's say , in LR6 it is not fixed.
