Even the simplest:
In the <head> of the page isn’t working. All my other browsers show it perfectly, including IE6.
Is this to do with the security settings of IE7?
I’m using the standalone version of IE7.
As far as I know there is no security setting that will prevent alert boxes from displaying in IE7.
Stupid question, but no errors/warnings at all were generated during the page load when you run the script debugger?
If you run it in Firefox, are there any errors/warnings generated in Firebug?
