This is what happens:
say this is the chat log:

-
Me: hey
you: sup?
me: Nothing much, you?
you: same
-
me: sounds fun
you: indeed...
me: well my textbox glitches

Ok, that's all nice, say the height is only 4 lines high
but when I add text and I have the selstart = len(text) it'll flash to the top of the box so I can very briefly see the top 4 lines then it goes to the bottom. I havn't experienced this with other programs, aol, etc.

I need something to make the scroll bar stay in the same place.
