What happens is this.

A grey bar (1" x 4" approx) will appear on some post to a thread. It blocks part of what's written. However, if ya go to the tool bar on your computer (if that's waht it's called) and go to view and then click either refresh or reload (depending on your browser), it clears the grey bar. The grey bar doesn't stay with that particular post forever. Seems random.

I have highlighted a post the grey bar appeared in/on and copied/pasted to Microsoft Word. The bar which was showing when I cut/pasted did not appear on the Microsoft Word page.

Wah sa pen ing?
