I looked into it a little bit; The case rule requires a number to fill in the row or column with, so there is a popup for the number to add. The popup window is in a do-while loop and waits until the number is set to something before moving on, which explains why the window doesn't close. It's in the getCaseBoard function within /skyscrapers/rules/CellForNumberCaseRule. However, if you cancel without selecting a number, the engine throws an error because there is no way to cancel a case rule after selecting it. Theoretically, if there is a way to tell the program to exit case rule mode, it would resolve the issue.
