System has worked flawlessly for months, no new software or hardware for some time. Other software seems fine & Alt-tabs fine.
Is it just me?
Follow these steps
Re-install DirectX8.1 or 9 first, whichever you are using.
Delete the file video7.cfg (ONLY this one file) which you will find in your HTC AH "settings" folder which controls video settings in the game. Moving and saving the settings folder elsewhere would update all settings as a new install, but the above file is the only one that should be causing the problem.
AH should now redetect your video settings and it generates a new video7.cfg file when you restart it, so don't worry about deleting it

If that doesn't fix it, set your desktop resolution to the same setting and resolution that you run in the game, and see if that works. Sometimes it won't switch properly if the normal desktop and game res and refresh rates are very much different to each other. If you change settings for video, always re-run the video settings button when you start AH, so the vid file updates your new setting.
If it still causes the same problem , re-install your current video driver and re-run the directX install again after.
