Thanks, that makes sense. However, do you have any suggestions on how
I might work around it? I want to be able to load all of the data on
startup, so I have called the PHP function that calls the javascript
function in the <body> of the .php file. I tried to throw in a PHP
sleep to delay the javascript from being called, but the sleep seems
to also delay the loading of the module, thus really giving me no
benefit. Any other suggestions would be great.
