Thanks for your time. Hope to hear you.

I would probably just update the system, by going to
asterisknow.org/install-related
be warned though that there is a new branch of the gui, 2.0 and I am not sure if it will keep your settings that you have now. It may require you to re key your system.

I found the problem which is the IE7 and new Firefox version 3 because when I use the older version2 I got no problem.
Thanks for the reply Riddlebox.
