Hi, I have a page containing the JS window.resizeTo(w1, h1); window.moveTo(x + (screen.width - screen.availWidth), y); and htmlunit complains with com.gargoylesoftware.htmlunit.ScriptException: resizeTo is not a function. I would like to know how we best deal with these errors. Where and how to apply patches/additions? any ideas? cheers Mittie
