Unity bug? gimp->xsane and firefox->fatrat

[Leander Jedamus]

Hi!

I got an issue with unity here on Ubuntu 12.04.
When I use firefox and start a download, I am asked what I want to do 
with the download. I select (FlashGot -> fatrat). Now when I minimize 
this fatrat-window, I can never get it back.
This also happens when I use gimp and select to create an image with 
xsane. When I change windows with Alt-Tab, xsane is not there and can't 
be selected. I can only kill the processes manually.
Both the windows (fatrat and xsane) have also no entry on the left side.

Can anybody reproduce this "feature"? I think this will happen to all 
programs, which are not started directly from the bar on the left side.

Thanks in advance
