we've GroupWise 80 istalled and we're getting the following problems after update:

Rights to Shared Folders can't be modified - I just have to "unshare" it and share it new.
Other Problem with documents what are shared in past versions - if I add somebody I want to share the document with - the addes user can find the document but all other user the document is shared can't find it any more.

Some idea what I can do to fix this?
