When I edit a case in Fogbugz, at first the edit box is about 8 lines long. As I type the box grows.

What happens to me is when the box grows my cursor (caret, insert point) jumps to the top left of the edit box.

We are using FogBugz Version 6.1.39 (DB 630, Build 214) I am running IE 8 on Windows 7

My co-workers don't see this behavior. Any suggestions?
