[Bug 41301] Re: Mouse clicks stop working sporadically

[Markus Berndt]

I am having the same problem. It usually occurs when my T41 wakes up
from suspend to ram and network manager connects to my wireless network.
When it shows the signal strength icon in the taskbar, the mouse is
useless. All I managed to do is Ctrl-Alt-Backspace. I'll have to try to
switch the desktop instead, next time it happens. This problem occurs
intermittently.
