My MacBook is in the shop being repaired so for the time being I'm using my PC. I've reinstalled Windows and loaded Dreamweaver on it. I have a Creative Cloud subscription and running Dreamweaver version 12.2 Build 6006. However, Dreamweaver constantly freezes. I could be opening a file, or just typing and it'll lock up. It's definitely not my PC, I'm running Windows 7 Ultimate x64 SP1 (all updated), Intel i5 @ 3.20GHz, 8GBs of RAM. The only thing I could think of would be my hard drive? Although other programs aren't driving the struggle bus like Dreamweaver has been.
May or may not be related to your issue, but I've had to use this fix for years: http://helpx.adobe.com/dreamweaver/kb/hang-opening-document-dreamweave r-cs5.html
