I've spent the last day playing with the beta1 windows package, but I'm having
a problem with getting maps bigger than 600x600. The current version creates
images around 800px square, but when I switch to 5.0 the biggest I get is
600px sq. I did ask on IRC without a reply so I'm trying here. Is this a bug,
or do I need to change something to get the new build working with existing
maps?
