Excel scroll bar bug
Microsoft Excel 2008 for Mac has an irritating bug where only the active document window has scroll bars. If a second document is open, or even if you only have one document but Excel is not the front-most application then the window has no scroll bars and ignores scroll messages from the mouse. This happens in Excel 12.2.0 (and a couple of earlier revisions behave the same).

The correct behaviour is for scroll bars in inactive windows to be drawn in an inactive state and to allow scrolling even when the window is not front-most.
I rather like Excel. I thought it was the least crashy of the assorted junk Microsoft released as Office 4.2 for Mac back in 1993. Fuck me that was a pile of shit.
