John, thank you for your attention. I'm so sorry, it seems this was an error on my side, but I don't really know. After I deactivated and reactivated the Windows decorations in CCSM everything is working fine. I also did a gconftool- 2 --recursive-unset /apps/compiz-1, but I think the unseting-resetting the windows decorations in CCSM is what solved the issue.
THANK YOU! ** Changed in: thunderbird (Ubuntu) Status: Incomplete => Invalid ** Description changed: + SOLVED: unset + set "Windows decorations" in CCSM did it for me + + *********************************************++ + 0) login using unity 3D on LTS 12.04, all updates applied 1) open terminal 2) start thunderbird: ~$ thunderbird & 3) minimize thunderbird window 4) start thunderbird again: ~$ thunderbird & --> Thunderbird window pops up but doesnt have a title bar, you can't move the window.
