Corrupted nessages list screen

Still getting this problem:

If I open a message that has never been opened before and then hit the BACK 
button to return to the messages list, the screen has some corruption at the 
top, e.g.;

-- Sections. Folders, Create Messages, Preferences, Etc. -->

And all the sytle info is lost.  This only appears to happen after opening a 
new message.  Is there something special that happens in this case as 
opposed to re-opening an old message?  Does sqwebmail create this message 
list page somewhere on the server such that I can see it - maybe then I can 
tell if the page is corrputed at the sqwebmail creation level or if Apache 
is maybe corrpting the page when returning it to the browser.

Thanks.
