[REBOL] Re: Button en-/disabling revisited
From: kpeters:otaksoft at: 27-Aug-2007 12:43
Thanks, Gabriele ~
that was just the hint I needed - things are looking a lot better now, although another
problem reared its
ugly head:
As you see, I have added a line to prevent disabling from happening twice (as it screws
up the button colors for good).
I would expect to see the alert the second time I press button 'b1 - it does, however,
only show upon the third button press....
Does anyone have a clue as to why?
TIA,
Kai
