Dreamweaver MX File_Save.htm Javascript error in File_Save.js

A colleague of mine was having this for 2 days. My suggestions were along the lines of Internet suggestions included reinstalling Dreamweaver and even reformatting! We didn't get to reformatting, but did get him to reinstall twice including a purge of files and registry keys missed by the uninstall first. No use.

Guess what? The problem was a corruption inside a file. Not a program file, but one of the files in a Dreamweaver project. Took too long to find because after all this was only a text file (.css). And we had already tried creating a whole new file and pasting the contents from the old one via a fresh copy of notepad. This copied whatever the corruption was. Doesn't make much sense, and how did the corruption get in into our file anyway. That's the kind of problems I used to get 10 years ago, seldom now.

Moral of the story: next time this Dreamweaver error happens, don't reinstall. Create a clean new file in the project with no content and rebuild the file. Don't paste the old text in.
