Great game, but display issues need to be fixed

My 5 year old loves the lessons and the game, but she is unable to exit from a game without closing the program and restarting due to display issues. There is no main menu or close option displayed on the screen of my Macbook regardless of what screen resolution I use. I loaded the program on a desktop computer and it appears that the close option is just outside the display range of the Macbook. I would easily give 5 stars if the display issues were corrected.
