I was using DW MX 2004 Education on Windows 2000 before when this would occur. I had no previous site definitions. I thought this was a 2000 issue so I waited on my new PC to arrive, which would be loaded with XP. I installed MX 2004 and had the same problem. I used the updates suggested by Adobe to no avail. So then, I uninstalled this version and installed version 8. I had the same problem with 8 and it's updates.
I don't get a dialog message upon the crash. It creates the cache, meaning that the scan goes all the way to the right and then freezes up ... everytime. Has anyone else had this problem? What can I do to get around this?
