That thread does not cover this really. This is different. It is not constantly crashing, and not responding. It ONLY crashes under exact circumstances and specific windows open etc. as explained. I think Jon also is showing that it does happen if you have this scenario.
PS: Jon, I do make my own work spaces as well. but since I have re-installed DW, and also worked with Adobe deleting cache etc etc.
all my personal workspaces are gone. So I am just showing you that even with the Default workspace and follow the steps, it crashes every time. It certainly is not my machine, my Windows or my install. It is a problem with Dreamweaver. Like you said earlier, I guess it is a bug... but this bug has taken up tons of time!
