Is there a guide somewhere to making a map from scratch using mapview? Took me a bit of fiddling with the save in notepad to get it to actually run.
There isn't really guide, i just don't have the chance to try this on my ownatm

Could you please describe what you needed to fix to get the map loading? It's definately not planned to have ppl fix the wbs by themselves after they saved it in MapView. I know about some important missing things, espcially the TeamId value for any kind of wbs files but the default civ4 file. But i guess i'm missing some "NONE" values aswell. I just don't have the time to go through the py file that does the saving those days.
Also, mapview seems to hitch a lot and drop update when laying tiles or moving / zooming. I usually have to click on the default tab and back to the map tab to try and fix it. Is there a solution to it? Is it due to using Vista64?
Hmm, i have it perfectly fluid and 100x100 maps usually run with 500-800fps in full view. I noticed some hitches sometimes but that's really rare and is often connected to the use of the selector tool. Clicking on tiles with units or cites might also cause spikes since the inspectors are rebuilt under some circumstances.
