"igfxext module has stopped working"

"Desktop Window Manager has stopped working and was closed"

Both times I just closed the offending window (x) and went about my work with what I believe to be no further difficulty. However, I'm not sure about this and the messages are concerning.

This DWM crash is caused by the Intel app not expecting there to be more than 2 displays connected to the PC.

It should be possible to stop igfxext running at start up to prevent this. The app only appears to manage the layout of external Intel displays, which Windows 7 does anyway, so you should not see any issues by stopping this process.
