I play SNGs and lately I've just had to quit because I time out every 2 minutes. I can usually still see the action going on at every table, but it just doesn't respond to anything I do and I watch as my hands get folded and I sit out.

Does anyone know why I would still have active internet connection, still be able to see everything happening on pokerstars, but just cant act? Is it my internet, their server, both?
