- Update 1 may 2018: With the new 'Spring Update' that has been released today the problem has been solved thanks god.
After the 'Windows 10 Fall Creators' update im having a problem with a lot of my software.
When i have a program that is using a 'SysListView32' component where you can select multiple files.
You will notice if you scroll down to the middle of the list by mousewheel or the scrollbars itself, and then try to select multple items,
that the mouse starts to go by itself to the bottom or top of your screen.
If you then try to keep holding down left button and moving in a direction, you see it's resisting, it wants to go to the bottom or top of screen.
Windows 10 Fall Creators version:
1 PC: Clean installation Windows 10 Pro, nothing installed except WinRar. To be totally sure.
4 PC: They had nothing in common with eachother, only that they all using a 1920x1080 screen and Intel i7 (860 up to 6700k) generation cpu
All the 5 PC's ive tested now when i scroll down to middle of list (SysListView32) at 'Icon' mode (but also 'Details' mode), and i try to select multiple items/files by mouse, the mouse starts to go to bottom or top of screen.
'Microsoft Windows Explorer', 'WinRar', 'WinZip', '7z', 'Ws FTP Pro'. they all have this bug now.
More applications i did not test with, it's obvious its the SysListView32 object.
Windows 10 Fall Creators version (Insiders edition):
1709 (17025.1000) and (17035)
1 PC: Clean installation Windows 10 Pro Insiders, updated with latest updates, nothing installed except WinRar to test.
For 'Microsoft Windows Explorer' the bug has been solved.
BUT. the bug remains for:
'WinRar', 'WinZip', '7z', 'Ws FTP Pro', and any non-Microsoft software for me.
I7 860 up to 6700k, 6 up to 16 GB, Nvidia 660TI up to 780TI, 1920x1080 monitors, SSD drives, Logitech mices (gaming and non-gaming).
I've even tested it to create a 'SysListView32' object with the 'CreateWindowEx' and stripped it to the bone.
Not even subclassed it or anything, and added 100 items to the list so that the listview gets scrollbars, then if you scroll to middle and try to select multiple items you see this bug happens.
Somewhere Windows 10 Fall Creators update is calling a 'SetCursorPos' API with the wrong coordinates.
Can someone please confirm this is a bug after the Fall Creators update?
Because this never happened before from Windows 10 all the way down to Windows XP.
You can test it yourself by having the Fall Creators update, then install rarlab.com (WinRar).
Then add 100 small files to a archive, then open the created archive with WinRar. Scroll down to middle of list, and then try to select multiple items. You will notice the mouse starts to go all over the screen selecting anything underway.
