Right after the end of a two round Wormnet game, when the statistic screen was loading, the game started acting up and the screen looked like this:

Then I got the fatal error message.

Attached is the Errorlog.txt and the Crash.DMP file.

Incredibly that looks exactly like a screen I had at one time, I think we (me + Cybdershadow) narrowed it down to FFDSHOW or a firewall.

Looks like something bad happened, but I wouldn't know what it was unless this could be reproduced.

I believe when the FFDSHOW dialog pops up the Front-end freezes (refuses any input). pressing CTRL ALT DELETE to minimize W:A will reveal the FFDSHOW dialog but it won't render properly, like moving it around leaves a trail, moving stuff over it leaves trails of that window on it, etc.

I'll test it.

I don't think that ffdshow is the culprit, because it's not in Plainplane's module list (as opposed to three of your crash reports - 1 (http://forum.team17.co.uk/showthread.php?p=588080) 2 (http://forum.team17.co.uk/showpost.php?p=589016&postcount=12) 3 (http://forum.team17.co.uk/showthread.php?p=657953)).

That dialog there looks like a vanilla-themed attempt at the MFC awards screen to me, i've had the same thing happen before but only once and it was yeeeeeears ago.
