ACTransit Cross-X Tiles

Hello,

I'm starting to use Modest Maps, well, I can't seem to find good examples and sample source code, nor the tutorials/manual (just the ACTransit).

Also I was able to follow the ACTransit example but it misses something. It gives me plenty of Cross Tiles and in standalone it gives the following output:

More, it makes to much zoom out to the point there's a tiny map square and the rest are cross tiles!

Using Flash AS2.

Thanks in advance.
