I like Dion's suggestion of an easier way, but I do not believe GW7 uses dictionary files. The only reference in the Registry is to the WT61EN.MOR file located at C:\Novell\GroupWise\
Whenever a user launches the program thru Citrix, the key pointing to this file gets created automatically in their profile. I have tried giving my test account full privileges at the root of the C:\ drive on the Citrix server with no luck getting spell check to work. The error message is:
"There is an error in the Speller Checker's Windows Registry information".
