Access violation RM9 on Mac with 2 screens

Suppose I select Publish to My Roots Magic, then select signin or create account, then cancel the dialog box to login to my account. If I am running RM9 on a single screen then everything works as expected. If I am running RM9 on the secondary screen of a 2-screen setup then I get a dialog box on the primary screen which says there has been an Access Violation error and I should restart RM9.
