Hi Paul,
Further ti my last email, I would still like to know about re-sizing the Hansa 7.2 window on Windows 10 but also I have additional info about the Win 8 App.
I havent tested lots of the functions yet and as you suggested, I deleted the Halcust folder and it ran again. But its when I try and use the Persons register the app closes and if I then open it again it gives me that error.
Thought that might help.
Kind regards
Dil
