This may be teaching you all to suck eggs but it's one of those things that I just do without thinking about, and it may help a few more of you out there. When you download Novell patches (expect for the tar.gz or .rpm type of course) you need to double click them and wait an indeterminate amount of time for it to 'Verify the security envelope' before the extraction fails because you copied it to My Documents, or some other location with a long name.
Well WinRAR is able to open these archives and allows you to extract individual files. Wahey, take that WinZip! Hope that saves you all some time, especially with the big GroupWise and NetWare patches.
