After clicking button...

In addition on the Netware 6.5 sp8 server where the Broker & Print manager are loaded you get the following at the Logger screen :

count -->1
FwUtils.................2544 com/novell/nps/gadgets/iFolder/LaunchiFolderTask (Unsupported major.minor version 49.0)
Task......................514

NDPS Library Error Category: 100000Dh
Other Error: 8915h

================================================== =======================

You get one of the above errors each time you attempt to do something using iPrint in iManager. I have several servers with iManager 2.7.2 & 2.7.3. The server that host the Broker and NDPS Printer manger is running NetWare 6.5 sp8 and iManager 2.7.3.

The problem can be cleared temporarily by restarting the server but after a few task in iManager creating or modifying print objects it comes back.

Any ideas?
