Modeless Dialog and CommandLine Prompts

[Kerry]

Does anyone know of a proven way to determine from a Modeless ButtonEvent whether there is a Command or VLISP prompt pending on the Command line.

I want to negate the button_onCllicked actions if there is a command Active/Pending.

I *THINK* the answer is as simple as clicking the Add Cancel button on the event pane so that the handler acts similar to a Menu call ie precedes the command with ^c^c
