Having shut down the PC last night & restarted the PC today, I find that having had all terms found yesterday, now only 3 of the 4 test files are found. Nothing changed just a restart ... My fake folder & fake files are all still there.
Clearing the fields & pasting in the term, or typing the term in manually, brings the 4th file type up OK, but my button won't.
Maybe there is some sort of bug here that would explain why it didn't work at all at first & now drops a component from the string list?
