unable to do anything

[CrosRoad95]

You can make player unable to do anything ( even escape key not working ) except closing game via task manager or alt+f4 via code:

local web = CreateWebUI(0,0,0, 0, 1, 32)
SetWebAlignment(web, 0, 0)
SetWebAnchors(web, 0, 0, 1, 1)
SetWebVisibility(web, WEB_VISIBLE)
LoadWebFile(web, "http://asset/"..GetPackageName().."/index.html")
ShowMouseCursor(true)
SetWebVisibility(web, WEB_VISIBLE)
SetInputMode(INPUT_UI)

Being aware of this since the beginning so I will mark this as "Won't fix" for now. If a server does this, they can probably be sure that player won't return.
If this ever becomes a problem in the real world I will check this again.
