Hi,
I’m using Corona Game edition and part of my game play require me to switch the image with physics body at the same location. If I do it immediately, Corona simulator crashes and Apple Bug reports open up. If I just add a 10ms delay, then it works fine.

Can you submit sample code so we can see what you are doing?
Thanks

So this is the code. If you uncomment the line 38 timer.performWithDelay(...) and comment line 37 displayBlue(event) then it would work fine.
