tso, to be honest I never anticipated or tested blank spots. I can see why it would fail. I guess you want an irregular layout, so can't just use the padding? I will look into this.

I have seen the corruption on animation. Clearly graphic effects are not my strong point. Scratchbox doesn't show the corruption, so I think it is something to do with the amount of processor time it takes. At least it is an option you can turn off if it bother you, but I will see what I can do about it.
