V4.0 Exclusive Button Groups [message #4364]

Here is one in what I assume will be many "How come IDL V4.0 handles
[insert programming concept here] differently than V3.6?" questions.

With V3.6, it was possible that an exclusive button group could have
none of the buttons set. With V4.0, this seems to be impossible, as
clicking on the button that was previously set does not generate an
event. I have lots of code where it is important that only one (or
none) of a list of conditions is set. I would like to retain the
"none" aspect of the conditions list, but it seems now I'll have to
revisit all this code.

Has anyone else experienced this behavior, and if so, is there a simple
solution to return behavior to that of V3.6 (without returning to V3.6)?

Thanks,

Charles
