Well after much angst I found the problem- but may have created another...  I took all of the configuration files from 8.5, copied them, and REPLACED the .ini files in X1D.  This solved the crashing problem!!  Now I'm getting a message saying the file was written by NEWER version of Sonar (which of course would be X1).  I save as a new file and all seems ok.  Will update when I learn more...
