>Is there a way in javascript to lock the page while it's loading? Sometimes, based on the content, when the user starts to click on an item, while the page is loading, this will stop the process and will generate errors. That is normal as the full content has not been submitted. Is there a way to avoid that?

A bit late, but if you're still looking for an answer.

For both IE & Netscape, initialise a variable ClickOK to false in the HTML header & setting to true in the onLoad event of the body of the document.

For IE you could then use (all clickable items need modifying, though this could be avoided with CSS & behavior's to attach events)

<a href="xxxx.html" onClick="window.event.returnValue=ClickOK">.....</a>

For Netscape you could then use the following, also in the HTML header :

function myClickHandler()
{
return ClickOK
}

window.captureEvents( Event.CLICK )
window.onClick = myClickHandler
