On several Windows 2000 Pro machines with the latest Netware client installed, we install the Groupwise 5.5 client. After brining up Groupwise, if you open an e-mail or begin a new message, the attachment window is transparent, and you can not see the attachments. You can still use menu options to open, view, or save the attachments, but you can not see the attachments. Novell knowledgebase says this problem relates to the MFC42.DLL file that needs to be replaced by an older version to work,but this seems to only work on Win 95/98 machines, and does not work on Win2000 machines. What can we do to fix this problem?
