Hi Jason Byrnes, thanks again for your prompt response and taking a look at the bug report - I'm sorry that didn't shed light on the issue. This is however the only time Dreamweaver has crashed after running it a year without difficulties.
I have two accounts on my iMac, one for me, and another for my son. My son does not have administrator access, and we are using Site Assist Professional for his new site. The full path to his site under "Places" is:
As I mentioned, the path doesn't appear to be the issue as a number of files from Site Assist are dumped into the correct folder. It's just that a little way into the command the script encounters a problem and crashes Dreamweaver.
