Alright, i was playing blockland normally as before.
then, i pressed the windows key and it brought me to the desktop.
Usually, i just open the blockland (program) again, the screen goes black, and after a moment i'm back on blockland.
But now when i open blockland if i have pressed the key and got to desktop, the screen goes gray, and it just stay's gray. I tried to wait, i waited 2 minutes, nothing happened (normally i get back to blockland in about 10 secs).
I am confused...
