I'm using a MacBook Pro and Windows XP in Parallels. In the latest beta, when I click on an item and hold down the mouse button, it gets "unclicked" even though I'm still holding down the button. This makes file organising by drag and drop very difficult for instance because the file will get dropped before the mouse is where I need it to be. I have tried two different wireless USB mice and they both exhibit the same behavior. I don't remember having this problem in any previous versions.
