Hi @scaustin34, okay thanks for the feedback. Good to know that the interaction library API is working as it should as we can rule out that you have a hardware issue which is also a positive development.

Calibration with the 4C is generally required to be ran using the Tobii Core Software System Tray Icon, so perhaps the calibration routine is faulty? Did you try using the tray icon then go straight to your Pro SDK program?

It would seem in any event that the issues does indeed lie with your project code, which unfortunately is not something we can offer detailed support on. My suggestion would be to run one of the Pro SDK sample applications to see if the issues persists there… assuming it does not, then further examination of your code would be required.
