Well I have the exact same issue with KC on my laptop. It's not every 20 mins but it usually happens alot when I'm in flight or in a big city or such, it does however happen at times when I'm sitting in the middle of nowhere with nothing around me as well. I figured it was just due to a poor graphics card on my laptop but I'll post up my specs anyways see what you think KC.

1. Gateway MX8734 Laptop
CPU: Geniuine Intel (R) CPU T2060 @1.60GHz 1.60GHz
Memory: 1014 MB
Display Adapter: Mobile Intel (R) 945GM Express Chipset Family

2. Not entirely sure how to find the keyclone id number, and if you really need my e-mail address I can PM it to you are you can just PM me on here.

3. Just one monitor for my laptop dual horizontal view, or horizontal span 2 windows stacked on top of each other, however you want to think about it :P
