Problem with radiobuttons in frames

[Ed & Clare Kelm <twopilots@xxxxxxxxxxxxxxx>]

    I have a program which has the following items on the main form:
    
    A frame with several radio buttons.  Call it FrameM.  
    Two frames within FrameM, each with several radiobuttons.  Call them
    FrameA and FrameB 
    
    FrameA and FrameB radiobuttons operate as expected: Pressing a
    radiobutton in either one only affects the other radiobuttons in
    that frame.  However, pressing a radiobutton in FrameM clears all of
    the radiobuttons in FrameA and FrameB.  This is new behavior which
    just appeared in the last few weeks, apparently with 3.22.  
    
    The screen shot below shows the result of pressing the "Normal"
    radiobutton in the frame labeled SWR. All of the radiobuttons in the
    frames labeled Source and Type of Plot have been cleared.
    
    Thanks for any advice!
