MX Simulator

so whenever i go to type a server into the bar i hit delete and nothing happens same with when i go to change my name it seems like theres a glitch or something, should i re download the .exe or is there a key on my keyboard i should hit because this started happening recently

like ill try to delete the server name in order to put the new one in and i cant delete it

Backspace should delete to the left and delete should delete to the right.
