SFML window freezes while it waits for data to be received

Hi guys.

Although I've already set my TCPSocket to non-blocking mode, the window still freezes (unresponsive) every single time when it is waiting for data to be received. I had tried to solve this problem with thread (with sleep and pause function) too but it didn't work though.

Windows will mark your application as "unresponsive" if you don't process events within a certain amount of time (10-20s). I've no idea how you handle things (since you didn't provide any information), but you have to handle events if you want to prevent your application from being marked as unresponsive.
