I have exactly the same problem - started all of a sudden about 3 weeks ago and as far as i know i hadn't changed any settings.
If the text box is full - the text I am typing has gone down out of sight. I have to manually scroll down to see if I typed correctly but if I start typing again it drops out of sight again.
I only happens to me on this forum and only once the text box is FULL..
Any ideas?
what browser and operating system are you using?
Dai, I kind of feel responsible for that, sorry mate, but hey now you have something you can do your mates PC just to wind them up a bit.
I am sure we will now see people with it at the bottom of there post as there signature, like the one that had press Ctrl + F4 for the secret mods section. (P.S. that's joke just in case you try it, it will actually close the window that is open and active)
I sometimes get the text going off to the side when someone posts up a large picture, but other than that not sure. Possibly right click on the desktop go to properties / settings and change to screen resolution and see if that helps it.
