Having loaded CAESAR II 2011 edition, I entered a complex, existing file which was created (on another machine) using 5.2. I made a few editing changes, then the file hung up. The graphics changed to dotted (!) followed by a complete shut-down and system re-start. This has happened three times now with the same file. I could accept a file abort, but killing the whole machine is a pain.

Has anyone else experienced a similar problem ? Or maybe it is the file that has an error ?
