first: thanks a lot for swfobject, it's very cool! i was looking for a flash plugin check with javascript and found it.
but now i run into a problem only concerning the internet explorer.
i created a document class that creates a new Shape and draws some lines, to see here: http://www.designerzone.de/test/shapeTest2.html in my project i'm working on, this swf is used on a PHP file which reads a filename from a database depending on an GET-parameter. so everytime you call the URL with another value for the parameter another picture will be loaded. this works well. so i created a file only drawing lines.
the confusing thing for me is that the lines in the background are away when reloading the page. this only concernes the internet explorer, in any other browser i tested, this is no problem.
