Thanks for the reply.

There would be about 6-8 objects I want to place on the stage so a timer, like you say, might be too intensive.

Is there a way I could use a grid type system and assign each object to its own grid (or area) on the stage.

The select at random, which objects to display?

That way there would be no chance of overlapping as each objects would only have one possible place it could be located, which would be unique to that object.

Any ideas?

Thanks.
