problem with fullscreen and frame-cmds

[simona bellavista]

I am using emacs over a vnc connection. when I use frame-cmds the
command-bar (the bar where one inputs the command name, variable name, etc)
disappears, because the window is too big for the screen. If I try to use
fullscreen, nothing happens, it doesn't work at all.

Does anybody has any hint?
