OK, it's what I thought. Somehow the shortcut isn't doing it's job. If you copy and shortcut to mb.exe yourself, it doesn't work either. I suggest removing it by hand from your base install, and re-installing. See if it works... You then copy and paste it over to your other ones (which you've also removed it from,) not forgetting to change the target path in the shortcut. Give it a try, anyway!
