Sometimes I get a message across my screen saying that I have a connection problem to a server.

Sometimes it happens at random points while I'm on a server. I could be on for at least a couple hours with no problems whatsoever, then the screen will freeze for a few seconds, and the message will appear. Most of the time it will continue after a little bit, but sometimes it freezes completey and exits me out and a little box will appear saying "Connection to server has been lost."

I was wondering if anyonelse gets this problem or if it's just my internet screwing up.
