Browsertest - Opera 3.50 beta9

Opera 3.50 beta 9 does not understand the 'indexOf' method of the javascript string object. Normally the javascript execution would terminate without warning, therefore I had to modify the page to also get the results of the other tests...

 You didn't see 'end of test'? - Then your browser stopped during the javascript execution!
(no results for screen object - javascript execution stops there)
