i think i have just what you need, two scripts, script1 connects to your isp via remote access, then launches remote access status (so you can quickly disconnect and then reconnect) and then launches Netscape,
script2 disconnects from remote access, then quits remote access status, then quits netscape. be sure to note the location of the applications and folders, you'll need to change these to suit your system. BTW i'm just learning about apple scripts so i'm sure these could be written better, but they work great. to make it work copy and paste these into the script editor and save as classic applet and check the box to never show startup screen. if you have problems i can email them to you.
