DO11: Click on File Display toolbar to change state

I have the default File Display toolbars enabled, along with the option "Click on destination's toolbar only changes state". However if I click on one of the close, copy, or swap button of the destination display, the button is activated. Is this by design?

Yes, the buttons on the right edge are special. (In particular, we thought it would be annoying to have to click twice to close the destination panel, with the extra click just to make something source that you wanted to close.)

If you want, you can turn off those special buttons and replace them by normal toolbar buttons (the new Go FDBBUTTONS command will turn into the buttons when placed on a toolbar). I haven't tried it but I'm pretty sure they will then behave like the other buttons on the toolbar (the ones on the left).
