I suspect this may be an entirely different problem, but since there are similarities, I'll rant...
My entire buddy list keeps disappearing for 5-10 minute interverals and then reappearing. While it is gone I have no im features, but am still connected to the internet and can browse websites. I have of course, done nothing to remedy this, except rant though, so really the point of this post is, I feel your pain?
Unless anyone knows how to fix it!
So I was sitting in my cubicle today, and I realized, ever since I started working, every single day of my life has been worse than the day before it. So that means that every single day that you see me, that's on the worst day of my life.~Office Space
