Hi, I have Horde 2.2.3, IMP 3.2.2 and use them on server with 500 users from 2002 without trouble. After we upgrade our workstations and install new IE 6 SP1 some users can't open your big mailboxes. When they use old version IE (IE6, IE5.5 etc.) imp working properly. Can you help me ? Lubomir Vogl
