I'm so sorry about that! I haven't heared about a problem like this before and am a bit clueless of what might cause it. What kind of pc are you using to play? A weak one might cause troubles, because of the level images, but I guess that would need to be an old laptop or so to be affected by that.

There is a fix for the client machine and a developer fix too (if this turns out to be the issue!)
