I rececntly developed an issue that ZFD7 Hotpatch 3 is suppose to
correct. I managed to get this patch though a Novell service request,

When I open the installer, browse and select my server then hit OK it
brings me back to the "Select target servers.." screen - and my selected
servers vanish.

I've tried running the install from multiple workstations with the
install files both locally and on the network. I've unloaded ZFD and java
on the target servers - I've even tried installing this patch on a server
with no pervious version of ZFD installed on it.

This is all on the Netware kernal. 6.5 SP5
