It's doing other weird things...
So? are you going to try what has been suggested, or are you just here to complain?
Jesus Christ. It's not complaining.
You can't identify a problem without stating the symptoms. If it was a bug, it's best to state any relevant symptoms to see if anyone else is getting the problem. If others are getting the problem you look for common factors. This is just a standard for Tech Support. I already had an idea of what it might be, but I wanted to make use by seeing if anyone else was having any strange or intermittent problems. As a matter of fact, I had just noticed new errors while in game and posted them here in a hurry.
If you want an example of complaining, read the above posts by Dwarf and Bama (especially Bama). Don't get snippy with me. I've been around since 2005, I don't need grief from some one like you. So either help, show some interest, or just don't say anything at all and get out of my thread.
Ranting aside.
It's as I originally thought it might be. It was probably not enough system resources. The culprit seems to have been FireFox, as it usually is with most odd problems. I still have some wonky issues with the interface but nothing more than normal.
