Comment 11 for bug 797795

Still exists in 12.04. I open qbittorent to download something or to continue downloading. If I select to hide qbittorrent in the tray icon it disappears. I can click hide/show many times and the window will not appear. I have to close qbittorrent and open it again to see the window but minimizing it to the system tray will eventually make disappear forever. You can only see the blue round "qb" icon on the unity panel.

As mentioned by Omer above:

"I believe when qbittorrent is minimized to tray, indicator-appmenu loses track of qbittorrent window and hence causing the bug, could be a bug in another component but indicator-appmenu IMO is more closer than unity."

This is exactly the problem here. Tested on a Intel DZ68DB Desktop on 64Bit, on a HP DV6000 32Bit and on a Toshiba Satellite 32Bit.

In the HP, Toshiba and the Intel Desktop which all use 12.04 all had the problem.

Is not annoying until the app is minimized.
