I can confirm the 2nd monitor mouse issue as well. When I run XP in full screen on the second monitor I have to click for anything to show up. Its frustrating because there are no mouse pointer changes when over controls on the screen. Like when you have two panes in an application and you can increase the size of one at the expense of the other (a splitter bar for those familiar with .net forms programming). Also tool tips, based on mouse position, don't display.
The problem goes away if running in OS window mode or coherence mode (the work around I am using now) in the second display. The problem also goes away if running on the main display regardless of the mode. I am currently using Build 3150RC2.
Did you ever find a solution to this?
