I'm trying to make my first scenario, and it's going ok, until I try to place a sign, or exit the editor.
When placing a sign, if I move the cursor around, many other unwanted signs spawn when I've got the text box up.
And when I click the red close button, or select quit from the file menu, the thing just sits there. It doesn't close.
Are these known bugs, or have I once again, managed to get weird errors because of my possessed computer?
