Hey guys, I am trying to click a button on a website with a WebBrowser control. This worked fine before, but once I put it into it's own thread, it returned an Object Reference not set to the instance of an object.
Any idea why it has done this? Any solutions?
The line that returns the error is indicated in the code.
Thanks guys!
