Hey cool,
Thanks PixelRebirth, I was not aware that created objects could be picked in the next toplevel event. That will make my eventing easier than waiting till the next tick. My assumption came by trial and error, but obviously I didn't try everything.
So here's a better solution to the initial problem:
Instead of rotating the objects the next tick, just add another toplevel "Start of Layout" event.
