what does this code do?

@phpnoviceJul 09.2006 — #

function MM_reloadPage(init) {  //reloads the window if Nav4 resized
 if (init==true)
 with (navigator) {
 if ((appName=="Netscape")&amp;&amp;(parseInt(appVersion)==4)) {
 document.MM_pgW=innerWidth;
 document.MM_pgH=innerHeight;
 onresize=MM_reloadPage;
 }
 }
 else if (innerWidth!=document.MM_pgW || innerHeight!=document.MM_pgH) location.reload();
 }
 MM_reloadPage(true);

That code is all for NS4, only. It automatically executes itself during page load and, if NS4, again each time the window is resized. On initial execution, if NS4, it saves the dimensions of the window as new custom properties of the [B]document[/B] object. For each subsequent execution (which won't happen at all if not NS4), it compares the values of these custom properties with the current dimensions of the window. If not equal, the code forces a reload of the page from local cache.

The purpose of this was that NS4 did not automatically re-render a document when the window was resized.
