I think I figured it out and I think it is a combination of bug and environment.The path to the files that wouldn't open were: D:\Crestron\Programs\¦¸ Archived ¦¸\Project\Panel.vtp.I think the ¦¸ symbol is causing issues. Now, before I get all kinds of "well, you shouldn't use that in a file path" feedback, it IS an allowable character, so I'm not sure why VT would have an issue with it, unless it dates back to early VT days where long filename support had just come out. I put that symbol in the path 1) so it stands out and 2) so it alpha numerically sorts to the BOTTOM of my folder list. Outside of that folder, I keep projects I am currently working on, so I don't have hundreds of folders to sort through to find a work in progress.?If i move the VT file outside of that Archive folder, it opens fine. If I move it back in, doesn't open.I also keep 4x PCs organized the same way, which is why it acted this way across all of my systems.
I reported the finding on Labs and they've got a bug logged.?
