I have used gotoNetPage which has worked, but without some kind individual posting the solution to use that method on the web I would've continued to try and use externalEvent.
Thanks in advance for any help.
I don't think externalEvent has worked since MSIE6, and even then it only worked with VBScript.
It works by acting like a bridge to a Flash movie, which in turn uses its external interface to communicate with the browser. It doesn't seem to work on MSIE9 (not on my system anyway); I suspect the localConnection is failing to be established (probably due to some security measure).
Or ... you could just use Flash altogether.
Thanks Dee, I wll look into that.
