Sorry, I'll be more specific this time.
New game, click on application in the project bar, then click on edit in the properties bar to the right of layout 1 in the event sheets section, right above manage event sheets | Add/Edit.
The window that appears isn't maximized, and the title reads: Event sheet: Layout 1. That's the window that doesn't display correctly. Clicking the bottom left corner where it says "event sheet editor" won't crash it until an event is added. Adding an event also fixes the display issue with the window.
