well, if you're using xtra editor, then you should carefully follow these steps:
1) rage at yourself for getting such a bad map editing program
2) rage at your computer for accepting such a bad map editing program
3) thoroughly delete all xtra editor files, folder, paraphernalia, wild animals, pieces of candy, etc.
4) go get SCMDraft 2
5) congratulate yourself for completing steps 1-4
no need to heartily thank me, of course.
*no offense, general mengsk, none at all....

xtra editor just needs a little bit of ..... upgrading.
