Hi all,
forgive me but here is another question, not-so-evident for me.

You have to realize a blinking message, or an object which periodically swaps 
two images :
think of an alarm icon.
The alarm is sounding, and the icon keeps alternating red/yellow horn images 
until the user pushes the ack button.

Use a timer to blink... but things are not always "smooth blinking".
Not a big problem, anyway... just would like to know if there is a clever way 
to assure a smooth blinking
(usually we are speaking of small objects).
