[Octave-bug-tracker] [bug #54720] Opening a msgbox, warndlg etc. after dialog freezes octave

[Rik]

Follow-up Comment #4, bug #54720 (project octave):

Confirmed as well.  This could also be a problem with the dialog code itself. 
The example from the help text for dialog


## create an empty dialog window titled "Dialog Example"
h = dialog ("name", "Dialog Example");

## create a button (default style)
b = uicontrol (h, "string", "OK",
                  "position", [10 10 150 40],
                  "callback", "delete (gcf)");

## wait for dialog to resume or close
uiwait (h);


doesn't work for me.  The callback is never activated and I have to close the
window in order for it to work.  In 4.2.2 the code stops after the uicontrol
object is created, which works, but then the uiwait code fails because there
is no handle h.
