Comment 6 for bug 310752

Thanks for reporting this issue. I notice your panel is vertical. The icons as shown in the image are for Thunderbird, maximized; for Firefox, normal window not maximized. If you click the icon in Thunderbird, does the window change? Also, if you click in Firefox, does the window move to the right and the icon change to match Thunderbird? Is this reproducable if your panels are placed horizontal, as installed originally?

I could not reporduce this using Xubuntu 8.10 with horizontal panels.

Thanks in advance.
