Sometimes, when I'm writing a new thread, or even replying to someone elses in advanced mode, it overtypes what I've written. Like if I wanted to put in something before "sometimes", it would overtype that word. I think I've noticed it most when I edit my posts - I often find errors and try to ammend them .
Any ideas why it doing that/how to stop it etc?
I'm using firefox, but I think it also did it in IE when I used to use that too (could be wrong though).
