Hi hadw
Thanks for your suggestion about using the alternate layering (cycling, transport and humanitarian). These all work fine but I prefer, at this stage, to work with the standard rendering / layer which for some unknown reason isn’t opening properly. I’m always left with two or three ‘greyed in’ squares covering the part or street of Venice I wish to look at more closely.
I am using Windows 7, 64 bit and are viewing the map of Venice directly from https://www.openstreetmap.org/. I appreciate your help. Thank you.
