Comment 5 for bug 120634

OK apologies I have just tested and found this is a GNOME theme problem. I had tried extensions and Firefox themes but problem still occurred. But I noticed the problem didn't exist if I was logged on as root so I changed my user's appearance/them back the Human theme and the problem seems to have disappeared... now to workout what s causing the problem in the theme because I really like it :-)

Best Wishes,
Steve
