I'm trying to detect if a toplevel, modeless form is running. I'm trying something like:

if type("test_form.width") = "U" &&it will be "U" if form isn't running
do form test_form
endif

The type is always "U", even when the form is running. I have considered using amembers(...), but if the form isn't running, amembers(...) throws an error.


Anyone have any other ideas/corrections? Thanks in advance.
