Hi,

i am building a VJ app that has a preview window in one projector, and the actual output in another projector window.

is there a easy way to clone the preview window for the main output?? or will i have to use something like the local connection to pass lots of varibles betwen the two projectors?

basscially i want whatever is displayed in one swf to be mirroredin the other.

cheers.
