Is anyone else experiencing similar issues? Running Parallels Desktop 10 for MAC, dual monitors in full screen. Both Windows 7 and Windows 8.1 Pro have major mouse issues. Called support and it was painful at best to watch him troubleshoot the issue. Issues are: If dragging a selection box from the top of the screen toward the bottom, the selection box behaves as if the mouse button was release and pressed again while dragging. Same occurs when dragging items around. The mouse button will disengage and reengage while holding the button down and most of the time it causes major havoc like inadvertantly dragging the wrong items, unable to make a selection box or highlight text properly, So the tech support guy changed the mouse options in the guest PC config but none of them worked quite normal and basically I had to choose between two options. Deal with this issue or have a mouse pointer that jumps around and accelerates erratically. Does anyone else have these issues or can offer better solutions that changing the gaming mouse option in config?
