Re: Silk not able to recognise child window on repeting a testcase
From looking at your code and guessing what it does, I'd say that it is vulnerable to timing problems. I would suggest watching the Runtime Progress window carefully looking for moments when the time it takes the browser to 'do its thing' is so long that a step in the sequence doesn't 'get through' and everything goes to hell from there. Click(), for example, might not raise an exception if the thing it is trying to click isn't even there yet. Once the click is missed, the following steps can't possibly work.
