Hi Steven,

Cheers,��

Hello everyone,

I'm new to pharo, and was writing a simple 2D game with Athens for rendering to practice a bit. I'm loving the environment so far, developing the game while it's running is really enjoyable :-) .

However, when the game is running, the pharo image will freeze at a random time. Alt-. doesn't make my image back to normal, the only solution I found is closing my image and opening it again, until the next freeze...

I don't really know what to do to investigate this bug, there is no output from pharo about this. The only thing I thought about is starting from a fresh image, importing my code and running it again to ensure it wasn't some messy state in the image I was using, and it froze even when running my code from a fresh image.

What can I do to debug it? Do you need more information to give me a direction?

Just in case you need it, here is the source: https://www.dropbox.com/s/pfn7ccw27i4nqr7/Creakout-debug.st?dl=0

Thanks,
Steven R��mot
