created an printer in iManager 2.7.4 on OES2 SP2 Linux with all patches.

Trying to manage the printer from an XP workstation, selecting drivers,
a window pops up with Content "Drivers" and stayed forever. I close this
window, the OS list states Linux. When I try to select an different OS
the same Windows with content "Drivers" pops up again and Linux is
selected again.
Also Internet explorer reports this error: "'profilePrinterModels' is
null or not an object" Line: 134 ...
I restarted all iPrint related services and I tested with IE 8 and
FireFox on XP and Windows 7 i386 but non worked.

Any ideas how to solve this issue?
