Hi Karl --

Take a look at the following places to better understand, why we must not use #addDeferredUIMessage: in #actOnClickFor:

TextMorph >> #mouseDown:
TextEditor >> #mouseDown:
NewParagraph >> #clickAt:for:controller:

The expected control flow in the #mouseDown: handler is synchronous. Hmm... I recall a similar issue with #mouseDown: vs. #mouseUp: when implementing other buttons.

Usually, the reaction should be in #mouseUp:. In TextAction, the effective reaction is currently in the #mouseDown: handler of TextMorph even if TextEditor waits for this MVC-style mouse-up event in a loop. Hmm...

Best,
Marcel

-1 bc. wrong place. See senders of actOnClickFor: and my other answer. Let's work on that (bigger) issue after the release.

Best,
Marcel
