Just encountered this while climbing out.
Was in P-51D, 75% fuel, 4th Fg skin. In autoclimb from ?61 on baltic, headed NE, full throttle. Opened clibboard, settings, icons --- messed with colors for enemy 1 clibboard ( from pure yellow to orange and back again), then squad icon (moved from purple to yellow, checked map, went to orange). When hit back to check map again, got hard lock, black desktop, and windows error recovery dialogue. Sound continued despite message that AH had to close. Task bar was visible. After about 10 sec, the rest of desktop (icons etc) retuirned and sound stopped.
Running Windows XP home 2002 with current updates, Pentium 2.8 gHz, 1GB ram, NVidia GForce 6600 GT with driver version 7.7.3.0. Sound through SoundMAX Integrated device.
