This may be a Windows 10 Mouse issue. But man is it annoying. I'm using the latest build Vegas Pro 17. I'm trying to complete a rough edit, so I am working with several tracks or stacked events and I'm using the selection tool to split those tracks. The issue is that the selection tool keeps dropping some of the events that I selected and or moving the events. Does anybody have experience with resolving this issue. I have followed several methods of resolving the Windows 10 mouse issue to no avail. Including purchasing a replacement mouse, uninstalling/reinstalling the mouse driver, checking for an update, and updating Windows 10.
