Comment 4 for bug 1278688

OK, I found the problem.

For some reason this trunk build conflicts Window 7's default security settings, meaning it will not create new files within the operating system hard drive, nor will it allow you or the game to edit any files.

Kind of strange considering it didn't do that before...

A couple of small things I noticed with the Map Editor:

1. Loading a map from the main menu screen seems to be locked into the skirmish folder and won't allow you to browse other files.

2. The music doesn't cycle between all of the game's tracks, it only picks Alliance only or Horde only tracks. It always starts with Horde music first, til you decide to go back into the editor again, then it switches to Alliance. Gets kind of annoying hearing the Horde music loop over and over, it's like an endless Zales Jewelry commercial that you cannot mute without shutting your sound off. lol
