This used to happen last Thursday then it stopped (not sure what I fixed) but the crash from 'View Custom fields' problem remained.
Now the crash problem is fixed with a new login, this other problem is back!
The fact that her old login used to work in XP but now has the same problem after using Windows 7, seems to suggest that the Windows 7 has corrupted her user account profile or something?
Therefore the new login account allows her to use Service Manager without the Custom fields crash, but she can't use anything else in Accpac now.
