Does anyone else have this problem? Sometimes I select a quote and then try to post a response after the quote. But, when I punch a key the content in the box will jump upward so that I can't see the letters I just typed in. I have to move the letters into view using the slide bar on the right. It only happens once in awhile, but it's real annoying.
Can't say I've noticed that, but perhaps that happens when you're quoting a lot of content?
Try extending the size of the reply box by click-dragging the bottom-right corner of the box so it holds all the content...
