Here are two differences in Hypercard; I'll gues they apply to Rev.

If the button is a member of a button family, clicking on it will
hilite it and unhilite others in the family; sending mouseUp won't.

If the button is autoHilite, clicking on it will deselect anything
already selected; sending mouseUp won't.

I spend a lot of time once debugging that first difference before I
realized what was happeing.
