WordPerfect9, GW client ,Windows XP

Hello all,
I updated Windows 98 PC with Corel WordPerfect 9 to Windows XP. Since that I can not save a document in library anymore, it just hangs and I have to kill WordPerfect and start over. It saves the document into the library, I can check from another PC. I can save document on network in application dialog, without GroupWise client. The network is stable, servers patched. GroupWise 5.5 enchancement pack. Novell client for Windows XP beta. Any ideas?
Thanks. Please send your ideas to i_bbb@yahoo.com
