Subject: [BeOS] Spelling dialog / support
From: Christopher Plymire (chrisjp@eudoramail.com)
Date: Tue Jul 25 2000 - 06:30:34 CDT
Finished spelling dialog resource.
Created code neccesary to operate the dialog correctly under BeOS.
spell.rsrc and should be inserted in /abi/src/wp/main/beos -- needs to
be marked as binary.
I've included diffs of the files neccesary to hook up these dialogs.
