I am using the latest version of the Cute Editor as a control on the administrative pages of my web site.  The web site is hosted by a server inside our LAN.  I have noticed a peculiar phenomenon.  When I attempt to do an image upload (which should result in a browse dialogue coming up, which allows me to browse to an image, select it, then upload it) while accessing my web site OUTSIDE our LAN, the "Upload" button grays out after being clicked, but the browse dialogue never comes up, the "upload" just hangs at that point.  However, if I access my web site from within the LAN and click "Upload" in the insert image dialogue, I get a browse dialogue, can choose an image, and can upload it.  Why would the upload not function when I access the web site outside the LAN?
