For the past few weeks I was getting an interesting problem on G&T, but it seems to have solved itself.
Basically anytime I was writing a post, it would lag after a few letters were typed, only to fill in the rest of what I typed a few minutes later. Led to some hilarious spelling mistakes, but it was pretty annoying. Would last anywhere from 5-25 seconds. I'm using the latest version of Opera, and the problem seems to have fixed itself, but I did think it was interesting.
