Hi, I have been using the hosted demo to investigate the Zimbra functionality. An important feature for me is the ability to edit an instance of a recurring appointment. When ever I try this in the demo it errors. I couldn't see any reference to this problem in the bug list - so I'm not sure if this is known limitation, or an issue with the demo host.
I have replicated this issue when adjusting pretty much any single field of the appointment. I am connecting from a Mac (10.4.9) and have tried with FF 188.8.131.52 and Safari 2.0.4.
PS I did click the "send error" button if that goes anywhere useful.
