I've been corresponding with Rob to try and remedy this problem, but so far we haven't been able to figure it out. So, I thought I'd appeal to the community here to see if anyone has any ideas.

Problem: When switching one of my slaves into my main window (F8-12 keys on my setup) both the master and slave will see their framerates drop to unplayable levels (<5). I have to typically either exit all 5 WoW sessions or reboot. It doesn't happen every time. I can play for a couple hours without the problem before it occurs or it can occur on my first window switch. Extremely frustrating.

I run 5 instances of WoW on a single monitor. My setup is an AMD Athlon dual core 5600, 4 gigs of RAM, and a GeForce 8800 GTS card. When playing normally I sustain around 40 fps on my main. Settings in keyclone are Maxfps 60 and Maxfpsbk 15. When it doesn't happen my performance overall is just fine.

My booster (usually in the last slave window) has a full set of addons. My four boostees have a fair number of addons as well. I'm not sure if my addons are at fault (either the specific ones I run or the volume).

Anyone else have this anomoly? Extremely frustrating obviously.
