I understand what the problem is.
I'm trying to create my own MENU, for my commands,
with an OpenDCL palette . . .
So I send to Acad, all the commands, from this menu . . .
But continuosly ACAD says "AutoCAD command rejected: . . ."
The solution is
that I have to set in OpenDCL
the property of the buttons "Event Invoke"
to asynchronicus and
NOT to synchronicus ! ! !
I hope this will help to who will find the same problem !
Thanks to all.
Ciao
