Mupen64 hangs after loading ROM

[euph]

I set the graphics plugin to be Glide64, checked "Get frame buffer info" under "Frame buffer emulation" (so I can play Dr. Mario 64) and played Dr. Mario 64 for one game and it worked! The only problem is now I can't get Mupen64 to run after I load a rom (I've tried Mario Kart 64, Super Mario 64, StarCraft 64, Star Wars: Rogue Squadron). It hangs after 2 seconds of "thinking" and enters the "paused state". The window loses focus and fails to regain focus (can't click it.) I have to kill the process in the task manager.
I tried reinstalling it, no luck. Help?!

CPU: AMD 3500+
Video: nVidia GeForce 6800 GT
RAM: 1 GB DDR 400
Mupen64 0.5.1 with Glide64 v0.8 Wonder

Go to Options->Settings
Then, go to the Advanced Settings tab and unselect the "Pause emulation when window is not active" option.

That worked thanks! For some reason I also got a mempak error but after clicking cancel it worked. Thanks again!
