Animation freeze

[curry]

Has anyone ever made an arcade style game in Rev, or anything else 
that used a lot of animations with "move without waiting" and "send 
in time"?

I can't post the scripts as-is, I'd have to try to make a simpler 
script to post it here, but what I've seen with two or three 
different projects is that Rev can unexpectedly freeze visually, 
until you press Command-period one or more times to interrupt it.

I'm not using any "wait until" statements, just "move" and "send".

Has anyone experienced this type of freezing and does anyone know a 
good way to avoid it or workaround?

Thanks,

Curry
