The particular item that I pointed you to is about 15 lines, and half of that is telling you were to make a change in various versions of Dreamweaver on Mac and PC (not too long, once you get to it that is) and I know it has helped quite a number of people with similar issues (this issue fixes all manner of issues that Dreamweaver seems to bring upon itself, and isn't specifically related to any particular extension). I've re-read it and not quite sure how it (#4) could be stated in a way that is clearer or even shorter.
Given I'm sorry that this has happen and I do understand wanting things to just work and understand wanting to turn off things that aren't.
Best of luck.
