I have an application which uses Netscape on NT and my client has asked for a 'Do you really want to exit' prompt when they click the 'X' in the upper right corner. Is this possible? I have looked through the prefs.js but nothing jumped out at me. <br>The application does use HTML and javascript. I tried the onUnload at the page and frame level but this doesn't work either. <br>Any input will be appreciated.<br>TIA <br>Lief
