How do I turn off OSX screensaver when playing games?

I am using a wireless Xbox360 controller for windows (with a USB dongle receiver) and my Mac screensaver kicks in during game playing, which I assume is because I'm not using the keyboard or mouse.

I don't want to turn off my OSX screensaver - I just want parallels to recognise that the computer is being used when I'm playing a game with the xbox controller.

I'm using parallels 5 under 10.6.2 on a 27" core i7 iMac.

Thanks in advance.

 

Anybody??!

 

I've run into this when using an console emulator - so it may be more a Mac thing than a Parallels / Window thing.

 

I too have this problem when using MAME and the Xbox wireless controller via the Wireless receiver. Can anyone fix this (other than turning off the OS X Energy Saving and screensaver)?

Os X Lion 10.7.1, Parallels 6.0 latest build, Windows 7 SP1 x64 guest.

 

12 years, I want to know the same, it's still happening and never got fixed.
