In one user installation, the program crashes when closing the last collision diagram on the screen. The only known specifics are: The user is running Window 95 on an HP Vectra 166/32. Norton Antivirus is in background.
This sounds like a timing issue, unusual to experience with current operating systems and recent versions of Intersection Magic.
We’re still investigating this one. It seems to work fine when selecting File / Close diagram rather than the ‘x’ button on the window itself.
