Again, I did a series of tests to help pinpoint the problem. I reinstalled a fresh copy of 10.4, installed 10.4.1 update, and CorelDraw worked. I updated to 10.4.2 and CorelDraw worked. I installed 10.4.3, then same crash again! I think this is reason enough to say that 10.4.3 messes with CorelDraw, but I still don't understand how I was able to run them properly together before I had a system harddrive problem. Hope this little bit of info helps.
