Hello Peter.
Firstly, I created another user account on my Mac and when I log into it and open InDesign CS6 - I do NOT get the "Cannot open resource file" error. Secondly, I opened the same document as before and when I click on a text field InDesign does NOT crash. It appears that the error is somehow tied to my main account although I went through the process to delete and recreate the InDesign Defaults and InDesign Saved Data files as I described before.
I pasted both the Apple crash report and the Adobe crash report on pastebin.com as you suggested.
Here are the links:
Adobe crash report link: http://pastebin.com/MkuPtcqj
Apple crash report link: http://pastebin.com/GzV4k1jF
I hope this info helps.
Thanks for your assistance with this.
Alan
