no more menu highlights when hovered

I've only had my macbook pro for a few months now and I haven't had many problems.

but lately I've noticed that when I go to a menu like say in firefox the file, edit, view, etc. If I click on file then hover the mouse over edit, edit won't automatically opens. I have to hold down the mouse key and hover. same with the submenus, arrows within the menus. this has really started to upset me.

anyone else have this problem? anyone know of a fix?

my machine is a macbook pro with 10.5.4

bubs

fixed itself. seriously. didn't work for a couple hours then all the sudden no problem.

Oh well. it works right.

if you hold your click for a tinny bit longer it, you have to hold and hover.. if you click fast you don't have to hold and hover.

its there for people who want to save a click, holddown-hover&select-releaseclick instead of click-hover-click

its different.

I would click fast and the none of the menus would highlight.
