I'm having problems after upgrading some machines to NwClient 4.91 SP1
Portuguese, as after that any application trying to print to a NDPS printer

The problem only happens (1) with non-administrators; (2) with
automatically distributed printers.

If I try to view print properties, I got an error message from
Explorer.exe: "The function address 0x2267dd8 caused a protection fault
(exception code 0xc000005)
Some or all the property pages may not be exibited"

The workstations have Windows XP Sp2 with all patches from windows update
