There are 3 pages in this forum alone with people complaining about the program, I am not alone here. You May be one of the luck ones, I do not know how you actually use Dreamweaver, whether it is for simple HTML or what BUT, It does crash a lot there are other posts in other forums that describe the same issue, even outside of Adobe, Inside Adobe, I am sure that there are Different "Discussions" regarding the same problem.
Studio 8 WAS the last totally stable version of Dreamweaver. CS3 had a few minor glitches BUT from CS6 onwards, it was forever and is still faulty.
