ugly tabbed buttons

[rand valentine]

 hi, all. i notice in my stacks that my tabbed buttons no longer look like
nice tabs, but instead look like a thin, sectioned bar with a displaced drop
shadow behind them, ie, they don't look like tabbed buttons anymore, though
they still work okay. something crashed the proper gui for tabbed buttons.
and when i create a new tabbed button, it has the same hideous appearance.
is this a bug in 2.2? or did i wreck rev somehow? i'm using latest panther
mac os x. thanks.
