The behavior you're describing is indeed odd. Does the recorder not find anything at all or does it only find the main window but not any of the controls inside it? If it can find the window but not the controls, this could be a bug, but if it can't find anything at all, it might be an incompatibility with the recorder. In either case, we would need to investigate further, we might need to get help from the support team on this.
This is a rather old question so I must ask, have you managed to solve this issue at all? I'm asking because if this problem is still persisting, this sounds like a case for getting the support team involved.
