When I write code in the Ver0.2.0e code editor and run it, I get an error.
The error seems to occur around the end of _init().

However, if I save it and double-click the icon, it works without an error.

Like this

function _init()
 window {
  width=200,
  height=100
 }
end

function _draw()
end

It's fixed in 0.2.0f. Thanks.
