SYMPTOMS
When a dialog box appears in response to a user pressing an arrow key to
select an option button on a dialog box, the user cannot immediately close
the dialog box by clicking OK.
CAUSE
IsDialogMessage causes multiple BN_CLICKED messages to be sent when the
focus is on an option button. This is due to the simulation of what happens
when the option button has the BS_AUTORADIOBUTTON style.
RESOLUTION
Use the dialog editor to remove the BS_AUTORADIOBUTTON style from the
option button, and then call the CheckRadioButton member function in each
of the radio button handlers.
STATUS
This behavior is by design.
MORE INFORMATION
Please note that removing the BS_AUTORADIOBUTTON style will not allow DDX
to work with the option buttons.
