Hello,

I am trying to edit esp -file, I have opened Script edit window and changed script.

But when I trying to close script window it asks me to save script, and when i push "yes" button it dont closes the window.

Is it bug?

There's probably an error in your script but NV's GECK doesn't report scripting errors. Download http://www.nexusmods.com/newvegas/mods/41642/? and try saving your script again while using it, if there is an error in your script it'll tell you now.
