[quote="madster":2asfdwwm]Freezing is normal if you're previewing fullscreen. Windowed doesn't have that issue and is thus encouraged.[/quote:2asfdwwm]
It happens windowed, too. Mine freezes all the time. Loading and saving freezes and often takes a long time even when loading a set of just 20 230kb's images. My computer is way beyond minimum requirements, is brand new and in tip-top shape and runs every other program I have flawlessly. I've even taken the same images plus backgrounds, put them into xna and ran them and they ran fast, loaded fast and saved fast with no problem.
I hope this is being looked into, and I hope this issue can be worked out at some point.
