Poorly-Named Dialog Buttons

David's comment on my last post made me think about one of my pet peeves that seems to be pretty common: Cancel buttons that don't really mean cancel.

For example:  Open a text file in Notepad.  Do a "Replace" (Ctrl+H):

   

After replacing some text, press the "Cancel" button.  What?  It didn't cancel my replacement?  Oh, I guess "Cancel" really meant "Close."
