Hi Jim,

    How are you trying to do the delay that you mentioned? With a "Delay 
forDuration:" kind of call? If you are doing that it won't work because 
that Delay will block the UI events processing.

    The only way I know to make timed things on Morphic is with the 
stepping mechanism. If you don't  know how it works just check the 
following methods on your image: #step, #stepTime, #startStepping and 
#stopStepping. Take into account that with #step you wont be able to do 
the flashing effect in only one method as you were describing. But that 
is because Morphic wasn't intended to be used in that way.

    If you don't want to use the stepping mechanism then you will be 
doomed to do the UI events processing yourself. Instead of using Delay 
you should  make a while loop with something like this:

    [done] whileFalse: [
       self world ifNotNil: [self outermostWorldMorph doOneCycle].
       "check the elapsed time and set done accordingly"
    ]

    Hope it helps.

Regards,
Hernán
