What type of dashboard are you specifically changing to?
LabVIEW dashboards should appear on LABView as you're running them.

Java and C++ should use SmartDashboard, but I would think at least a white window would show up when you switch types. Otherwise, if you try to run custom dashboard code, then that should appear on SmartDashboard as you are running the program.

However, (if this is your question) if you're running any other dashboard type, then the default will no longer show.
