Multithread/Background function execution in Rev?

[nfeasey at utpress.utoronto.ca]

Ahhh.

The following code...

show button "myButton" with visual effect dissolve
wait 2 seconds with messages
hide button "myButton" with visual effect dissolve

...allows messages to proceed through the message path so that other
elements can be clicked or typed and the only interruption is when the
actual show and hide commands are in progress.

Lovely.

If anyone has any further suggestions for improving how this would work it
would be greatly appreciated but this is certainly on the right track.

Many thanks to all who responded.  Still not working as I want it to I'm
afraid.

I tried using the send command and Revolution still wants to complete the
dissolve before relinquishing the keyboard back to the end user.

It basically wants to finish this sequence...

show button "myButton" with visual effect dissolve
wait 2 seconds
hide button "myButton" with visual effect dissolve

...first and then relinquishes command back to the keyboard for user input.

I want the above sequence to proceed while the user continues to type input
into various fields that are on the screen with NO interruption.

Possible?

P.S. Dar, I would be very interested in your primer.  It would be a very
interesting read.111

I took the Hello World tutorial an an example and changed it as below. 
It is interesting that if you start the visual effect first, it seems to 
block the "move field".  But if you do it the way I have below, it works 
on Windows and Linux (although clunkyness may be platform dependent I 
suspect).  To me it seems that Revolution is mutithreaded sometimes.

Am I doing this along the lines of what you were suggesting?

***the card script:

on preOpenCard
   set the loc of field "My Field" to -100,-50
   hide graphic "My World"
end preOpenCard


on myWorldMsg
   show graphic "My World" with visual effect dissolve
end myWorldMsg

on myFieldMsg
   move field "My Field" to the location of this card
end myFieldMsg

***the Start button script:

on mouseUP

     send "myFieldMsg" to me in 1 milliseconds
     send "myWorldMsg" to me in 300 milliseconds

end mouseUP
