I tried it, and it crashed the program. I got to the point of having the dialog open showing both elements, side by side. I made a couple corrections of the sizes to make them exactly the same , then when I hit the Swap button it crashed, with the 'send error report" dialog.
This was with the latest version, 1.37a
I tried it a second time, and it did not crash, and it now works as I want, I can click the label and it changes state.
thanks, MachScreen is a gem.
