I seem to have mislaid your reply to this message.

I conducted the following experiment:

1       Set up a new test project from scratch.

2       Turn the backup files preference OFF.

3       Make a new class.  Change a method and compile.

4       Add another method and compile, then quit BlueJ.

         Only a *.java file created.

5       Turn the backup files preference ON.

6       Make another class, change a method and compile.

7       Add another method and compile, then quit BlueJ.

         Created *.java, *.java# and *.java~ files.  Then the *.java# 
file became *.java#backup!  Possibly Windows Explorer slow in refreshing.

8       Launch BlueJ again and double-click on the last class.

         Error message about BlueJ crashing appears.

I often Quit all projects, leaving it to BlueJ to save files before 
it exits.  Could this be somehow different from saving each project 
before quitting?

Regards,
Hedley
