X crash on multi screen set-up

[jebusthesaviour]

Thought I'd submit to the mailinglist before filing a bug report.

System:
Fedora 10 x86_64.
3 * 1680x1050 displays.
2.6.27.12-170.2.5.fc10.x86_64 #1 SMP.
nvidia nvs 440 graphics card, has two GPUs and 2x2 DVI connections.

What happens?:
Reoccurring crash, involves mouse click triggering some sort of event
which makes further mouse clicks unavailable.
Can still move mouse cursor, but as mentioned after the event no more
clicks are registered.
Short time later X crashes. Keyboard can be used throughout, just mouse
is affected before crash.

Notes:
Never happened with Twinview on dual screen set-up.
Seems to happen only with Xinerama. -"Is it true that with a 3 screen
set-up you can only use separate X screens?"
Xorg.log looks error free.

Hope this information helps.
