Buon giorno, ho questo problema.Ho inserito un Panel, nella pagina, che viene richiamato tramite un pulsante( linguetta.png).Quando clicco, scende per un tot di pixel, quando ri-clicco torna su...

Ho visto che c'è un problema, se apro il Panel, e poi, con lo scroll scorro la pagina, questo Panel mi segue, e fin qui ok, ma se clicco sulla linguetta, per chiuderlo, con FF ed OPERA, invece di salire, scende ulteriormente, creando una "schifezza", invece con IE è tutto ok..

Vi posto il codice js, sperando possiate aiutarmi a risolvere questa schifezza

codice:
var panelWidth = 280;	// Width of help panel	
	var slideSpeed = 15;		// Higher = quicker slide
	var slideTimer = 10;	// Lower = quicker slide
	var slideActive = true;	// Slide active ?
	var initBodyMargin = 0;	// Left or top margin of your <body> tag (left if panel is at the left, top if panel is on the top)
	var pushMainContentOnSlide = false;	// Push your main content to the right when sliding
	var panelPosition = 1; 	// 0 = left , 1 = top
	
	/*	Don't change these values */
	var slideLeftPanelObj=false;
	var slideInProgress = false;	
	var startScrollPos = false;
	var panelVisible = false;
	function initSlideLeftPanel(expandOnly)
	{
		if(slideInProgress)return;
		if(!slideLeftPanelObj){
			if(document.getElementById('dhtmlgoodies_leftPanel')){	// Object exists in HTML code?
				slideLeftPanelObj = document.getElementById('dhtmlgoodies_leftPanel');
				if(panelPosition == 1)slideLeftPanelObj.style.width = '100%';
			}else{	// Object doesn't exist -> Create <div> dynamically
				slideLeftPanelObj = document.createElement('DIV');
				slideLeftPanelObj.id = 'dhtmlgoodies_leftPanel';
				slideLeftPanelObj.style.display='none';
				document.body.appendChild(slideLeftPanelObj);

Scusate se è troppo lungo, ma spero possa esservi utile a capire.
Vi ringrazio e vi auguro una buona giornata
