slow typing

Hello, I'm having some issues with slow typing. Not me, but the forum seems to go in "slow mode" sometimes??? I have to press a key several times before the character comes up on the screen. I notice the auto save flashes each time it goes slow. Can I turn the auto save off to see if its the cause? I'm on my work computer at the moment (don't tell my boss!) and its doing the same thing.
Interestingly enough, its not doing it on this page??? It was freaking out on the pen, wood and private message pages. No scrap that, its freaking out on me again now!!!

any help would be great,

Thanks,

Ash.
