I created a little VBA addin with a class similar to the clsSelect described in the "Interactive Selection" section of the COM API Reference. The class has a Pick method with a loop that does DoEvents while waiting for events to be fired.
If I make a Test sub that uses the Pick method everything works fine: Inventor waits for the click, allows for zooming in and out or clicking other ribbon buttons. The events work as expected.
But if I run the same Test from the _OnExecute event of a button created on the ribbon, the interface freezes and no event is fired.
I tried also with buttons created with the ribbon customization interface. The result is the same.
How do I prevent the interface from freezing when I start a command from the ribbon?
Thanks,
Stefano
