Mac OS X 10.7.3 and iPrint Client 5.04

hi guys,

anyone experiencing some problems with the new mac os x update 10.7.3?

- printer installation wont work (safari or chrome). installation runs in a timeout.
- user authentication wont work: client wont ask user for his credentials.

i already did an iprint client reinstall, machine reboot and i installed the printer manually... no improvement.
i just got one mac os x 10.7.3 machine so i cant do an failover check with another 10.7.3 machine.
with 10.7.2 everything seems to be fine

thx in advance,
martin
