I want to preface this by saying that I haven't had time to do any exploration of this myself so I could be overlooking something but -

I have been at two client's offices in the past week that are rather remote and use a DirecWay satellite link to the internet, Zimbra just doesn't seem to work.

The login screen loads fine but upon actually loging in I receive a very broken page with no images and nothing but basic text. Now I'm really wishing I had taken a screenshot.......

As anyone who has used these satellite links in the past will know, the latency is horrendous at best which brings me to my question -

Could this latency be causing timeouts within the Zimbra UI and thus breaking it? Both machines are fully patched and updated windows machines running XP and IE 6 so that shouldn't be a problem.

I apologize for the long post for such a short question, but wanted to provide a decent amount of info.
