You can use breakpoints. The program will pause as soon as it hit the breakpoint. To add breakpoints, right-click in the place where you want it and set it. You can also set probes. The probes activate as soon as the information is available. Then you can be creative with the highlight execution, breakpoints and probes. You can have a fairly good idea on how your program is executing.
Otherwise, try posting your code or an image of your code so we can try to figure out what is going on.
