chrome / opera rendering

I tried samples, dhtmlx.com/docs/products/dht … ntext.html for example. Ok in Firefox 5, IE 9, Safari 5 - but down for Opera 10.50 and Chrome 12
Do somebody know why? It’s a bit ennoying, cause I thought the product was working ‘out of the box’ on all modern browsers…

Menu opens in Chrome by right click. However, you need to use ctrl+click to open context menu in case of Opera.
