Today my host moved my files to another server, and tested them there. 
  They appeared to work there.  Please go ahead and close this ticket.

Here's the last thing my host said today on the matter:



We have not heard from the developers. As was explained earlier, we 
can not check with horde developers directly because it is not 
installed by us, but by cpanel developers. What we can do is move your 
account to another server. If that does not help, we will install a 
fresh copy of horde in your account which you can also customize for 
your own needs.

I  apologize if this is the wrong queue.



When using Netscape 7.2 or Firefox 1.0, with certain messages,  when 
you click Reply or Forward, you get a blank window that you cannot use.



I have already reported this bug to my host (jaguarpc.com) through 
their ticket system.  Ticket number is 2131033.  Masood Nasir is the 
employee who worked the ticket.  They have not resolved the issue.



Be advised that this is NOT the same Mozilla layout bug previously reported.



I have created an e-mail account that shows the bug happen for one 
message, but not the other.    The user ID is 
"testuser@mikesmedley.com"  and the password is "test".
