Just as I was wrapping up about 10 hours' worth of work on a file, I tested some of my newly created buttons, each of which performs a script. I started getting messages that said "This script cannot be found or has been deleted." — not with all buttons but certainly with ones I hadn't touched and which had previously been working just fine.
Despite the alarming message, the script did exactly what it was supposed to after I clicked the "OK" button in the alert dialog box.
I opened up the "Manage Scripts" window and performed the identical scripts from in there, again without any problem, but this time without the alert message.
I closed the file and re-opened it. Same problem.
I closed the file and ran recover on it. Same problem.
I couldn't find anything under filemaker.com support that mentioned this particular problem.
Anyone here got any ideas?
