GUIRegisterMsg() callback documentation...

[Ultima]

The GUIRegisterMsg() documentation needs updating. It's difficult to determine what return value would cause AutoIt to stop handling the message internally.

From the manual:

By using 'Return' without any return value the AutoIt internal message handler (if there is one for this message) will NOT be proceed!

Yet, an empty return *does* allow AutoIt to continue handling the message. Returning 0 does the same. It seems that it's only when you return a non-zero integer that it stops handling things internally.

So yeah, clarification/reorganization would be nice :)

Additionally, the example script no longer works properly (though that problem might originate from the possible regression described in ticket #222)...

The documentation is correct, the behavior is bugged and it is related to your other ticket. AutoIt is supposed to stop processing the message if you use the "Return" keyword, period. The only exception to that rule is if you use "Return $GUI_RUNDEFMSG" which is the only way to use Return *and* allow AutoIt to use it's own internal handler.

I'm closing this as a Duplicate of #222. There is no bug in the documentation, just in AutoIt.
