SysListView32 mouse selecting bug after Windows 10 - Fall Update

Dear Microsoft 

You know you can use the api CreateWindowEx to create a 'SysListView32'.

If you have created a listview with API, then set it to large icons, or details mode.
Now add 100 items to the listview so that you will get a vertical and or horizontal scrollbar.
Then scroll to middle of the listview.

Try to select items, you will notice the Listview will move the mouse cursor to the lower corner or top of the screen.

This happened after the Fall Creators Update (of october 2017) version 1709.

The component that Microsoft updated to point you in the direction is 'mscomctl.dll' which has the bug.

(since Windows XP, up to vista, 7, 8, and 10 (before the Fall update) this always worked perfect.

You can try this bug with WinRar, WinZip, 7zip, of any program that using a Listview (SysListView32).

Just add enough items to the listview to get scrollbars, scroll to middle, try to select multiple items, and voila, the mouse starts to move by itself all over the screen.

I've tested this bug on 4 different Windows 10 machines before and after Fall update.
On 7z forums (which is another proggy i use) they have the same problem).
Ive also tested it myself with WinRar and WinZip. both also having this bug.

Please fix this bug as soon as possible, my software relies heavily on the SysListView32 like a lot of other software.


Kindly regards,
