I recently needed to replace my old PC with a new Windows 10 machine. That meant doing a complete new install of all my software.
Now it seems that Windows OneDrive is interfering with the correct operation of ACP and Maxim. Briefly summarised:

1. All new files created by ACP are stored in a documents folder under OneDrive instead of the normal Documents folder.
2. The permissions for the OneDrive folder are "Read Only" and Windows won't let me change them.
3. This means that when doing a training run for pointing image files for plate solving cannot be stored and the script terminates.
4. Have tried uninstalling OneDrive, but the OneDrive directory is still present and cannot be deleted.
5. Moving the content of the OneDrive Directory to a normal documents directory doesn't help. I just end up with multiple documents folders and have no idea which one is actually current.
6. This problem arises essentially with all the Observatory software: ACP, Maxim, FocusMax, etc. It all gets shoved into OneDrive.
7. In short, my hard drive is now in a mess, and I have no idea how to sort it out, other than re-formatting and starting again. Please tell me that's not a good idea!
8. Help!
