Running Windows XP Professional.

For several games I tried, (I know, I know... it's only games) I get the following error on starting up the game:

"This application cannot run with an active debugger in memory. PLease unload the debugger and restart the application."

I can find nothing in the XP documentation about a "debugger". What is it, and how can I remove it, and would it hep anyway?

Thanks a lot.

Oh, one game I'm having this on is "Children of the Nile"
