A MAC with 10.6.4 installed. Then install the iPrint client v5 for the MAC. Then try and install a printer using safari (5.0.2), and safari hangs with the spinning coloured ball. Same as above, but install using Firefox, then printer installation works okay.

Some of our MACs were on 10.6.3 and iPrint client v5 already installed, and were upgraded to 10.6.4. These continue to install printers in safari as before.

MAC 10.5 with safari 5.0.2 continues to work if the iPrint was already installed. Not sure about a MAC 10.5 with safari 5.0.2 which gets a fresh/clean install of iPrint client.

Anyone else seen issues? For info - the safari update appears to have been released on 07 Sept 2010.
