When I try to write or copy text into the box, the lines jump up and down. So I can't see the line I am writing on, when I click on the end it the box jumps upto the begining but the curor is at the end out of site.

I think you may need new glasses Jim

Glasses are fine it's the eyes i think, or have I the shakes.

Nope...happened to me once or twice. Found that the scroll wheel on the mouse was caught in a "half-click" roll. Don't know if that's the issue, Jim, but roll the mouse wheel once before you post!

I've seen that here sometimes and on other bb's. I think it's only happened when I've been trying to edit a relatively long post. Does it happen after a certain number of lines or characters?

first time was when i was editing the stafford post to insert pictures.
second time was when I was editing another post.

Actually, it did happen with the last post I did. Once the text window filled up and it needed to scroll to keep up it started to jump. Very weird...

Ya, still going on. It only happens when you fill up the test block when making a post. As the block starts to scroll downwards as you type, it "jumps" continuously up, making corrections very difficult. I finally wound up making my post in NotePad and copy/pasting into the forums' text block.

I edited a post today and it still jumps back to the beginning
