In the Aleutians map I can only fly for a short while. The fourth or fifth time I hit range vox the machine locks up and (eventually) crashes to desktop. However I have to reboot at this point because AH will not run again (same 'encountered an error and must be closed').
One other strange thing is that it reverts my video settings back to 1024x768 (I use 1280x1024) and I have to change it back manually after I reboot.
