[QUOTE="sieler, post: 827598, member: 94817"] Problem found/resolved. The problem is bad programming at Apple. When designing a data file, one should incorporate a "tag" specifying what program created/updated the file, and what *version* of the program it is. Then, at file open time, iWeb should have had code like: If 'iWeb' tag not found, reject "this file not created by iWeb" else if version tag = my current version then // ok else if version tag < my current version then begin do what ever conversion is needed, if (a) necessary and (b) allowed and then continue as above end else // oh oh, it's from a newer version of iWeb reject "sorry, you are running version X of iWeb ... this file was created by version Y ... a newer version. Since iWeb doesn't know what changes may have been made in what was once the future, iWeb can't open the file. Please consider upgrading to version X. Note: there is some possibility that a version downgrade utility might exist. Google for "iweb version downgrade" ... or just upgrade. Did we say you could upgrade? " And, iWeb lacks that code. I'm surprised ... I wouldn't expect that kind of error from an experienced developer. Stan [/QUOTE]
