I sent this question to everyone:

To answer that, I'll say - you're probably correct in most cases, but for
reasons too complicated to delve into here, I *have* to do that. There's
no question about that.
In any case, for the user, a Tab is the same as a click in the control
the tab would have gone to! So, we're back to the drawing board.
And, you continued:

So - Does anybody know anything about the fix? I am using beta-2, so it
doesn't *seem* to be fixed.
