I would like the opposite...a way to delay the menu from coming down.

I often run VMs in Full-Screen mode across multiple screens but when I go to the top to hit a menu sometimes the Mac Menu pops down. This is very annoying with a maximized Windows window because I often hit the "full screen" button by accident causing everything to resize.

I agree this is a big issue when using parallels in full screen mode. I really like full screen mode with parallels since it gives me a quick way to have a windows machine in a separate space.

However two issues make this a pain:
1- the above issue which makes you accidentally drop out of full screen mode whenever trying to close a window within windows. The X close button is located in the exact same position as the hidden "leave full screen mode" arrows.
2- full screen mode doesn't work logically with multiple displays. It should work as a continuous line of screens scrolling across the displays but in fact spaces forces you to choose between one display set versus the other.
