Take a look at the permissions settings on the file and the folder(s) in which it is located. For some reason, the OS is not permitting changes to the file.
I did that and double checked everything, then closed out of the file. Upon opening it again, all was well. Don't know if thecking permissions helped, but everything is fine now.
Thanks for your input. I believe you have helped me before and I certainly appreciate your expertise!
Estilen, did you find a solution for this problem? I am having exactly the same roble as you did, I have throughly looked at all the settings and privilegies and can´t find what the problem is.
Graciela, did you check the attributes of the folders and files within, using the appropriate OS functions ? in Mac: Get Info, and Sharing & Permissions. In Windows: Properties, and Attributes.
