Hello all,

I maintain a software printer driver based on IPrintOemUni. When I try
to print using this driver (from any application) under a Restricted
user account, the application freezes.

The only notable feature of this issues that I've been able to narrow
down is that it occurs just before any of the DrvEnableDriver callbacks
are called. When running as a Power User, the driver is enabled (via
IPrintOemUni::EnableDriver), queried and released
(IPrintOemUni:isableDriver). A call to the DrvStartDoc hook follows
immediately. When running as Restricted, the hook is never called and
the client application freezes.

Any advice?

Hmmm. Have you tried running with the SysInternals FileMon and RegMon to see
if you can identify permissions errors which might be occurring?
http://www.sysinternals.com - it's just a great set of tools, and it might
give you a clue.
