Zimbra Desktop opens shared elements in browser

[deletek]

Hello All,
I have a problem with shared documents and ZD. My documents open correctly in ZD window, but shared documents are linked to http://server/... which causes opening document folder in browser (password prompt earlier).
My folders and documents point to Bugzilla Main Page via ZD service.

Server is ZCS 6.0, the newest client, browser: firefox. Confirmed to work the same on Windows 7 and Windows XP.

Please help or register this as a bug (I don't think it should work like that.

Thanks,
Piotr
