APM Handler

WinXP, Service pack 2, 768 RAM

I was burning a DVD using Nero, and have done so many times. It kinda froze and then I notice a screen that said "APM Handler" on my desktop.

Since the screen was frozen I coouldn't click on it to see if it said anything else but it looked like thet screen was empty except for "APM Handler".

I googled this but found no useful info. Can someone tell me what this is?

None of my virus detectors went off and Sygate reports nothing.

Thanks.
