I am having this error again and this time I cannot find the reason for it. I have two Web sites on my PC. On one Web site, the App_Data allows read write on the tables. On another Web site, configured with the exact same parameters, I always get this message when I try to update:

Cannot update the cursor VIDEO, since it is read-only

This is the same for any table. If I do the same command in VFP, it works. Anyone could recommend specific locations where I could look for in trying to resolve this issue?

On the first Web site, I don't have any impersonation. But, on the second Web site, I am force to define one in order to make this work. Why would the second Web site requires it and the first one not?
