I have a GeForce 9600 GT and with the latest drivers yes. It's all working beautifully again now. You really have made a thing of wonderment here. Only question remaining for me is: What does the "Mark" (the pink bar) actually DO? Obviously it's important, but how do I use it? Oh yes, and how do I REMOVE any ground textures (like paving) if I decide that I am not happy with it (and I mean after saving, reloading and then changing stuff) - obviously Unod would do this normally, but if I am reloading? The rest is now pretty self-explanatory. I wildly underestimated how big the XL size is - but that's fine, having two reasonably sized towns with bits of ribbon development between them and a few villages could be an interesting challenge (assuming I finish adding all the detail before the end of the year!). I like the Easter Egg of Colossal Airlines too for the hangar

. You should be justifiably proud of what you've done here!
