It seems as though when I run limewire, I cannot run it in the background along with a 3D application or game. When I do, the following occurs...

Loads 1 of the CPU's (Which ever affinity it is set to [HT processor])
Freezes the application, but not the PC
Continues to download queued files

You can still exit the program by right clicking the taskbar and clicking exit, however it cannot be done any other way except ending the task in the task manager.

Has anyone else experienced this, and is there a known way to fix it? I'd like to continue downloading files, but can't when it's loading my processor as it is, when I run 3D applications.

Things to note:

I have the most up-to-date directX and video drivers.
