Sorry Enrico - I didn't notice your post - thanks for reporting - it's
a pretty interesting thing.

> > Why NSButton doesn't implement - setAllowsMixedState: ?

I remember adding mixed state support to NSCell, and it is there.
So, adding -setAllowsMixedState: to NSButton is simple - I did it on CVS.

The problem is now - how do we show the mixed state to the user -
NSButtonCell has no support for that.

I guess someone with an OPENSTEP or NEXTSTEP system can suggest about
this...
