Beginner Level 7, lesson 5 Customer List Form 2. On "customer list form", select a customer, click to open the "customer form" for that customer.
  
With both forms open, what happens if the user clicks on the "customer list form" again, setting the focus to it?  Will this be covered in a later lesson?  I think I would know how to work out this issue, but I am curious if you have a solution or can send me to a lesson/video that discusses possible interference between multiple open forms.
