Comment 236 for bug 41301

I can confirm that the bug is only present when my Logitech G5 mouse is plugged.

Testing these past few days seem to suggest that the focus gets stuck only when I _use_ my Logitech mouse. In other words, if I leave the Logitech plugged but only use my laptop's trackpad or my Kensington trackball, the focus never gets stuck. Then the moment I move the Logitech mouse, without clicking anywhere, the focus gets stuck.

Furthermore, once the focus gets stuck, it is instantly freed by unplugging the Logitech mouse. Plugging the Logitech mouse back in instantly locks the focus to an object. The only reliable method I found for freeing it is to switch terminal (tty).

Today I brought my Logitech mouse to college and tried it on a PC running Windows 7. Within seconds of using my mouse, the focus got stuck. That's right: the exact same problem described by this bug report is present in Windows 7. Hitting Ctrl+Alt+Del and then Cancel freed the focus until it got stuck again. Same thing as switching terminal under Linux.

I really don't see how this could be possible. The only explication I can see is that the firmware inside the mouse somehow got corrupt. I tried to flash it from school, but Logitech only has flash tools that works in Windows XP. So until I can find a computer that still runs XP, I cannot confirm this theory.
