This could be a QuickTime related issue...

If you do not specify otherwise, RR will use QT for transitions.
But, especially on older and slower PCs, it takes a little (or more ;-) 
time to LOAD QT.

And QT is very memory/processor consuming!

You can "switch off" the usage of QT, then the RR built-in effects are 
In your case the built-in dissolve is a little bit cheesy ;-) but it 

Put this in the stack script and check it again:

on preopenstack
     set the dontuseqteffects to true
    ### do your stuff...
end ...

This way RR will not use QT for the transitions...

Hope that helps...

There is a trick concerning this phenomenon on:

-> Developer Resources -> Revolution

Scroll down to "QuickTime"

I am not sure, but i think so...

This is also the case when a stack is a "palette"...

Sorry, no idea.

You're welcome :-)
