Sometimes on my Macbook Pro when I have a lot of icons in the menu bar, if I start an application which has a lot of menu items, some of these icons get automatically obscured by the menu items.
For example, when running iTunes, the Twitter icon gets obscured...
...but if I switch to Finder (which has a fewer menu items) the icon then re-appears
Is there any way I can show or get to these obscured icons without having to switch to an application with a shorter menu bar?
