I'm 99.8% sure I haven't renamed any folders. My scripts are available in my IND>Scripts>Scripts Panel Folder, but they are not visible in my scripts palette anymore. I think this must be something obvious, as I have only seen one other person complaining of a similar issue (unresolved). I've trashed my prefs etc. I've been having this problem for a month or two, but am reluctant to reinstall. Does anyone know what my issue is? I am in IND4 on a 10.4.11 powerpc mac. Thanks in advance.
Okay, so Jongware solved my issue with this:
"As for your disappearing scripts, right-click on any script and select "Reveal in Explorer/Finder" (something like that, anyway). Are all your scripts still there? If not, there's your problem If they are, you could try to reset your preferences (http://livedocs.adobe.com/en_US/InDesign/5.0/help.html?content=WSa285fff53dea4f8 617383751001ea8cb3f-6d1e.html) (be sure to read Peter's instructions on how to save custom settings you might want to keep)."
I have never used a keyboard shortcut to reset my prefs, I always just trashed the folder; for some reason the keyboard shortcut did what manually trashing could not, and I have my scripts back.
