If anyone is interested, Victor Yee and I have put-together an AppleScript/Applet to delete preference files in one easy click!
Please look at the Read Me before using.
There is a run-only version and the script - which is editable. Feel free to use/distribute/change as you like, but if you alter it, make appropriate changes to the Read Me file.
Send any thoughts/suggestions!
You can download from my idisk: thebeatles / Public Folder / Preference Cleaner.
If you don't have OS 9.x, e-mail me and I'll send it to you.
