Dreamweaver CS6 hangs when opening file

Question

Starting recently Dreamweaver CS6 hangs for 30 seconds or more, sometimes saying not responding, when I open an HTML file. It appears to do this when the file contains links to external places. To test I created a file that contained nothing except the "new HTML file" basic headers, saved the file, then opened. This test file did not hang.
I have tried the registry fix "ResolveRemoteURLToIPAddress FALSE" and deleting the personal configuration directory (with Dreamweaver closed). Neither of these solved the problem. Dreamweaver still hangs when opening a file.
Any other ideas?

Once the document opens, check the code for any protocol relative links (links that start with // rather than http://) and change them to http:// links, at least during development. It is a know issue to Adobe and will cause what you describe.
If you don't have any protocol relative links, links to third party sites can cause issues from time to time if their servers are slow or have any kind of conflict with your network. Unless you absolutely can't, you may want to copy those external scripts to your local site and link to the local versions instead, again, during development.
