You should also let us know what kind of application you are trying to automate i.e. what is the client application (that provides the right-click functionality) written with?
Some apps don't follow convention and while it looks like a popup menu to you or I, it's some custom widget that makes it look like a menu. That could be why QARun is not seeing it or treating as it should.
If you let the board know what your app is, someone might be able to let you know that this is the case and advise an alternative.
