[Apololies is this has been discussed – searching for terms like “Numbers” and “Pages” doesn’t work too well and “iWork” came up dry]
On latest Snow Leopard (10.6.2), when I run Vine Server (3.11 1031) as a switched user (port 5901) and then access it via remote screen using various clients (COTS, Jollys) both iWork’s Pages and Numbers cannot display their template chooser properly. The template display rect is blank and, if you resize that window, you will see tons of slanted black and white lines – reminds me of the old days of braodcast analog tv. See attachment
