0.4.5 no menu bar

Having trouble with LMMS? Ask about it here.
Hi,
I have LMMS 0.4.5 on Ubuntu 10.10
I have no menu bar (Project, Edit, Tools, etc) :(
Any ideas why?
If further info is required, please let me know. :)

Cheers,
James
Any ideas why?
nee.. but why not upgrade? Current version is 0.4.12, and a lot of serious bugs has been removed since 0.4.5

neways... off to upgrade. 8-)

Cheers!!
