I don't know why I haven't posted this yet in the 2 month span of this problem roaming free in my client. This issue is a huge annoyance to me that forces me to restart Blockland every time I happen to alt tab and I'm not sure what is causing it to break. Whenever I attempt to alt tab from my Blockland client and switch back to it, a few things happen to my client:
-I cannot perform basic functions such as moving around (wasd) and toggling light, but I can still jet and jump.
-When I use the chat function, I cannot backspace the characters I've typed nor can I press the escape key to cancel it.
-Pressing enter forces me to toggle fullscreen (much like alt+enter) for Blockland.
To confirm that my computer didn't screw up everything, alt tabbing doesn't break any other games/programs I have.
