User-Agent: Mozilla/5.0 (Macintosh; U; PPC Mac OS X Mach-O; en-US; rv:1.7) Gecko/20040803 Firefox/0.9.3 Build Identifier: Mozilla/5.0 (Macintosh; U; PPC Mac OS X Mach-O; en-US; rv:1.7) Gecko/20040803 Firefox/0.9.3 When I launch, and at all times when I'm running, there is an extra window open... it's a small square window that I can only see when I hit F9 to invoke Expose - and then it appears. If I command-esc through my Firefox windows the mystery window is one that gets rotated through (I can tell because the other window will loose focus - although the mystery window seems to be positioned offscreen). The problem is that by loosing focus to this mystery window I get really confused why keyboard commands don't work on the window that appears to be active. What causes this window to appear? How can we kill it? Reproducible: Always Steps to Reproduce: 1. 2. 3.
