close sprite and animation editor

in ubuntu 14.10 with gnome shell the sprite and animation editor
don’t have the x button bar on top for close, how i can close?

This is a problem indeed with Gnome 3, you can try to right-click on the top part of the window and click on “Close”.

the top not exist, but i have found solution:
1 positioning mouse in the window
2 press menu keyboard key on the left of shift
3 click close on menu

Ok, will try to add a “Ok” and “Cancel” button to that dialog (to have another way of closing the window). :wink:
