Stop Games From Launching Web Browser On Close

Gametop,

I absolutely love your games, as I have younger family members that benefit from them and they love them. With that being said, I have put these games on a PC where many non-technical users are using the computer, and it worries me that a web browser is launched every single time a game of yours is closed on the PC. Can you please tell me how to disable that feature? I do not want any web browsers launching. If I can fix this issue, I will definitely continue downloading and using your games.

Thank you.
