It doesn't matter whether I have 3 or 5 buttons.  And it only does it to the 2nd option.  If I delete the button it appears again after the next build.  If I erase the group and create a new one, after a while the option2 button appears again.  Sometimes there will be 3, 4, 5 or more option2 buttons superimposed over each other.

When I run the application, Sometimes when that option2 button is there and I handle the optiongroup_propertychanged event, I get stuck in an endless loop.

Any thoughts?
