Comment 22 for bug 363375

Neat, I can replicate this bug. If on my second monitor, if I tail the Xorg.0.log and hold down Enter, I occasionally see *only* the "miPointerConstrainCursor: Invalid input device pointer" message...but nothing acts up. If I switch over to my third or fourth monitor however, I start to see "miPointerWarpCursor: and miPointerUpdateSprite:" errors. When holding enter, and I go to the third monitor, it will "jump" over to the fourth monitor....but I can go back "left" to my third monitor and that seems to work fine. However, if I go to the fourth monitor and the mouse hovers *over* any application (tested: gnome-terminal, firefox, vmware), it'll "loop" within the fourth monitor...over the application. If I put the mouse over the desktop, and then try to go back left to the third/second/first monitor, it works (this is all the while holding down enter on the tail).

Not sure if this clears up anything or not....but it is an interesting bug.
