ALL menus? Or just certain menus? I get a huge delay with opening lists of ships, colonies, etc. But not when opening the ship design screen or the empire options menu.

When you open a list the game sorts through the existing 'world' to find all of whatever you are listing -- ships, colonies, etc. This takes some time for some reason. Perhaps the highly compressed format of the game data causes this, or maybe it's just some problem with the many layers of code and MM could optimize enough to make the delay less noticeable.
