Hi Ray,
I'm still getting this Javascript error when opening a new file from a template. Ive tried deleting the macfilecache.dat file in the config folder but it does not solve the issue. (incidentally this file on a mac is located through this file path - hold down the alt key and select go from the top finder menu, then go to - library / Application support / Adobe / Dreamweaver / macfilecache.dat )
Any ideas?
