Hi,
we have got the following problem with the IE6/7/8:
After a user logs in, you can see the content of his Inbox. When you switch to another folder, your get the message "Serverfehler (OK!)" (= Servererror! (OK!) ) and the contents of the new folder is not displayed. When you then press "F5", the contents are displayed.
The problem doesn't occure on the Firefox or Safari, only on Internet Explorer.
Thanks in advance for your help!
