I apologize for posting an incomplete fix. Version 1.7.5.9 only corrected about 1/4 of the problem. I have just posted version 1.7.5.10 which should fix the rest of the problem. Here is a link: https://sourceforge.net/projects/switchwithit/ This fix corrects the problem with Yard Track Names AND Industry Spur Names that match existing IDs. It also corrects the problem with Yard Track Names and Industry Spur Names that have the first 6 characters matching existing IDs. Maybe I can get back to building my layout and completing a building for our MR Club layout. David
