Periodically through the course of gameplay, I hear a faint "beep" that is not part of the game's music or sound effects. The sound appears to occur randomly and it does somehow seem to be location sensitive (i.e. it is louder when the game is focused above whatever is causing it, quieter when it is off in the distance). I first noticed it while playing through the game's original campaign and it is still occurring now that I am playing the Aryn campaign. The beep was a very familiar sounding one, so I went through the Windows system sounds until I found that it was actually the default "Exclamation" sound (in Windows XP). I have checked Windows logs and can find no error or warning associated with with the sound event and nothing unusual has been happening in the game, so I'm not sure what might be so exclamatory. Anybody else experiencing this or have any ideas what might be causing it (or have an idea on how I can figure that out)?

EDIT - Well, looks like I figured it out. The sound was caused by Windows DEP interfering with the game in some way. Now if I could just figure out how DEP turned itself back on....

I can't give myself credit for the solution, so free rep to the first responder!

It seems to be related to some kind of swap file action the game is making, which is most likely causing some kind of minor buffer overflow; exactly the kind of thing DEP is supposed to prevent. I disabled DEP completely (its mostly a waste of time and processor cycles anyway) and now it doesn't happen anymore.

BTW - Free rep for you.

I'll definitely look into it next time around, thanks.

Oh, free rep is nice ;)
