No solution, just to say you're not the only one. I have ArcMap 10 (single user domestic / XP) and nothing happens when I try to create a group layer. Though 'something' happens because I can Edit/Undo it. ESRI won't help because I'm only a domestic user and search has thrown nothing up so far. My only course of action now is to get v10.1 and hope the problem's gone away. Roy Hi, I have not used ArcMap for 2 months and suddenly it behaves strange: When starting a new map from scratch, I cannot add a basemap and I cannot create new (basemap or group) layers. I see the option and can click it and there is not even an error message, its just: nothing happens. Even when adding a basemap, I see the selection window and can select, for example, OSM. But nothing happens after that, the program doesn't even crash... Any ideas? I am using ArcMap 10.0 thanks in advance, I could not find anything like this using search. Ben
