BUG: D4PL1 Radio Buttons on a Dialog cause lockup...

To duplicate place one or more RadioButtons from the tool box
(BooleanPresenter.Radio button) on a Dialog view.  Then test it.  As soon as
you activate one of the RadioButtons the Dolphin UI will lock up.  I have
been able to break out via Ctrl-Break.  I find that I have to do that and
terminate twice before I can close the view.  This also happens if you do a
show from the class browser after you save the view.

I can duplicate this on Windows NT as well as a Windows 2000, I have not
tried on other systems.

My quick workaround was to use CheckBox's with code that emulates RadioBox
functionality instead.

I am attaching the stack I get when I do the first break after it locks up:

This does indeed appear to be a bug and it has been logged. Thanks for the
report.

A better workaround might be to place the radio buttons inside a
ContainerView rather than directly inside the DialogView. This appears to
work ok.
