Saving maps?

*I solved the save problem*

Another problem, sometimes when I edit I suddenly just can't click anywhere, I click but it wont go in to what I am clicking on. What should I do if this issue happens again?

gui bug is caused by fast pressing "esc" twice, you probably want to close one gui window with "esc", then realize your mistake, and press "esc" again -> tada, bug occurs..

to fix it install 1.0.4 beta:

Is there a way to continue editing my saved map after that I close the program? When I check "Open" I can not find my saves maps there so I don't know..

Nightly builds bug the map editor, you wont see the icons at the bottom and cant test either. Just try to avoid pressing ESC twice really fast and also alt+tabbing ( this also bugs the menus ) and youll be fine.
