[Newbies] How to put a delay between Morph movements/changes ?

[K K Subbu]

Nicola,

Morphic updates to Display are buffered, so you can't animate them 
through delays. Morphic core already has built-in facilities to support 
animation in an efficient way. There is an excellent tutorial by John 
Maloney at:

See the section on "Adding Liveness" (page 11) for the specifics.
