Hi Tony Following the points you raised it would be interesting to hear from the list how many members share the data between ESRI Clients and MapInfo clients.
Presumably, although you only have read permissions to the SHP and TAB file other (ESRI) users have write permissions to the SHP file. I assume this because if all users see the file as readonly then the file might as well be converted once to MapInfo TAB and MapInfo users view that rather than rebuild MAP each time they open the file. Surely the benefit of not converting is to always link to the latest version of the SHP data when you open the file? So my question to the list is how many MapInfo users access SHP files that are being changed in realtime by other software packages? If your problem is that some users have write permissions to this file, but you only have read, then could you have write permissions to the folder, but read only to the SHP? This way you could create the MAP and ID files. I think your idea is a good suggestion for 8.1. If the TAB file is READ only then have a default path for creating temporary files would as you say solve the problem. If the SHP file was on a network drive it would also allow users to see the latest version of the SHP as they would build their own temporary DAT. What happens now?? Presumably if User A opens the Shaped TAB and stays on line User B picks up the MAP built by User A. But what happens when User A closes if User B is still on line...?? Any users with both MapInfo and ArcView and a network like to try that...?
