The way I do it is simple by pressing Shift and Tab, but first you have to modify your autoexec.lua to make it work.
Double-click on that file (located in your game dir), choose to open it with Notepad, then paste this into it:
Code:
screenmode = 0
function toggle_screenmode()
if screenmode == 0 then
taskbar_hide()
message_hide()
screenmode = 1
else
taskbar_show()
message_show()
screenmode = 0
end
end
bind("shift+tab", "toggle_screenmode()")
If you get "Game paused" thing even if game is not paused, press Pause button twice and it will be gone.
