Thunderbird crashes and locks computer when receiving messages.

This is the latest version of Thunderbird installed on a new, clean instal of Window 7. The previous installation on Windows XP has run for years without problems.

When Thunderbird locks up, it locks the whole computer. The mouse won't work and Ctrl-Alt-Del does not work. The only solution is to shut the computer down with the On button.

I've been fighting this for a week and I've been slowly working through the various 'fixes' that I find during a web search. I've disabled indexing and Lightning and I'm currently running Thunderbird in Safe Mode. I can't remember installing any add-ons but we have US English dictionaries running.

Any suggestions? It's driving me nuts and, since it's my wife's computer—well you know the rest. ;-)

I had the same problem, but found out the turning off hardware acceleration solves the problem (Thunderbird 38.1.0 on Windows 7 (64), Intel G41)

Uncheck "Use hardware acceleration when available" in Tools - Options - Advanced: General or set true for "gfx.direct2d.disabled" in configuration editor

For others who may read this, after posting the question, I opened Thunderbird in Safe Mode to see what happened.

After an hour or so, Thunderbird froze again—same story, could not close it or do anything but turn off the computer.

We've now been running Thunderbird for several hours after using the fix suggested by Platrix.

All seems well. Thanks Platrix. :-)
