I just opened
gvim on my Ubuntu (Hardy Heron) box and found there was no menu bar (File, Edit, etc).
After messing with some
guioptions and getting nowhere I ran
gvim as root (using
sudo) and the menu bar was there. The answer came from a forum post by “Marko”:
Delete the file
It will be recreated when you run
gvim again. With luck, the menu will be displayed again.
