I have examined the source code of both pages and the parent has three iframe tags (occasionally it has four), the child has none. I have literally tried interacting with every single ID, Class, Name, XPath, etc. on the child window and nothing has worked.
To attempt to confirm that the child window is indeed just generated by the parent window I used the getCurrentUrl. They both returned the same String.
I have tried the driver.switchTo().frame(0); command trying every frame available in a For loop, but I receive the same error that every element I try to interact with doesn't exist. I have also tried to switchTo().defaultContent and parentFrame(). The best I can do is interact with the parent window.
I am not sure if this is relevant, but the child window has the internet address about:blank (which is unchangeable), the title: Untitled, and has no Toolbar. I am using the latest version of Google Chrome.
Any help please? Is the problem iFrames?
