I use the method logDirection:andBytes: from the changeset RCX.1.cs .
This method uses WorldState addDeferredUIMessage:

	WorldState addDeferredUIMessage: [
	Transcript nextPutAll: dir;
		nextPutAll: string size printString;
		nextPutAll: ' bytes: '.
		string do: [ :ch | Transcript
			nextPutAll: (Character value: ch) hex;
			space ].
		Transcript cr; flush
	]

"Before", it was working, and now it isn't : nothing appears on the
Transcript.

When are the deferred UI messages processed ?

Thanks

Joseph
