ok this should be a simple one!

I am running a piece of software that when I bring up a menu it is larger in the vertical sense than my screen, when I resize I just lose the lower half. More or less this is preventing me from selecting "ok" to input some parameters into my software. i have toyed with the fonts and menu selections that are in the fedora distro (newest one linked of RH site). There used to be an option to allow the menu to overlap between workspaces, but I can't find where I set this in Fedora or is there another option? (BTW there is no interface menu control for this application)

Cheers,

DH
