AppleWorks 6

I cannot get AppleWorks 6 to open. - either by using an existing file or the app icon.

It worked OK until I changed my OS 10.5.8 to 10.3.9 - I was tryihg to find a file - I found the file and copied it - then went back to OS 10.5.8.

When I tried to open Appleworks the icon moved left and right but nothing appeared.

I have often moved between the two OS's with no problems

Cheers
