 In order to debug an application, you need to set a breakpoint. When the program gets to executing the line with the breakpoint, it will temporarily stop ("suspend"), allow you to inspect its current state and step through the program. To set a breakpoint, you need to double-click on the area to the left of the line you want to suspend the program at. After doing that, a blue dot should appear there.
