I've applied the patch mentioned in your 2008-03-05T13:21Z email,
and it takes care of all the concerns I had raised.

If you hadn't pointed that out, I probably wouldn't have noticed.

It's also possible to move the dialog so that the focused control
isn't on the screen at all--in which case no tooltip appears. I
have a couple of msw applications (both ms and non-ms) that take
care of that.

Yet how significant is it? I can move a dialog so that a text
control with focus is entirely off the screen, and I can type
into it, but I don't get visual feedback...so what?

The current situation is completely acceptable to me.
