I've written the following method to help me 'wait' for buttons as a page uploads.
StringBuilder buffer =
1. 20000 is WaitForElement's timeout therefore unless the button shows up within 20 sec from invoking the method, it should throw an exception. For some reason it looks like a delay is created not a timeout. Are you aware of it?
2. In addition, what are forms of HtmlFindExpression I can use other then Xpath ? Could you pls add an example?
