        Not quite. :-)
        Maybe we are talking different things... To recall: you don't
agree with the fact that UpdateIfNeeded() must be called from BWindow's
thread only?

        If that's the case I must remind you that UpdateIfNeeded() was
introduced to: "Forcing an Update while Responding to an Event".

        BTW, if you to this:
        with our current implementation, it's quite possible you won't
get the result you're looking for (ie. the rect being redrawn). Why? The
_UPDATE_ message may not yet have arrived in BWindow's port queue.
(remember what I told you a couple weeks ago?)
