Bugs:

	- internetexplorer geht der mausfokus der module fl?ten - evtl ist das kein richtiger bug
		kann aber trotzdem etwas verwirren
		(evtl wegen style cheet fehler, der bereits behoben ist...aber noch mal testen)
		
	- im internetexplorer fangen die scrollbars der module (sofern vorhanden)
		an zu flackern, wenn dragger und resizer ein und ausgeblendet werden

behobene Bugs:
	
	-im internetexplorer scheinen selectboxen durch divs und damit durch unsere module
		im internetexplorer werden nun hinter den content in die divs iframes injiziert
		um somit ein durchscheinen zu verhindern
		- Danke an Microsoft f?r diese tolle programmierarbeit -
