interesting. MouseClick() attempts to simulate a real user click on an element. On the other hand Click() works directly on the DOM structure of the app. Perhaps the clicks are occurring in very rapid succession. This could leads to problems with the simulate real click (i.e. MouseClick() ) since a real user would not be able to click around to rapidly.
If you're interested in getting to the bottom of this you can introduce a fixed delay in the test and check out whether that resolves the issue.
A fixed delay in code will look like this:
//Fixed delay - takes miliseconds as a parameter
You can put this like before you invoke the MouseClick() function.
