Stack Overflow Error
When you get a stack overflow error it means you need to add more memory
- edit the oxygen.vmoptions file that lives in your oxygen directory on your desktop
- on my desktop it is at this Path: C:\Program Files\Oxygen XML Editor 12\oxygen.vmoptions
- on my desktop I have the -Xmx set to 1024m (like below), however, you may need to play around with this until it works for your installation of Oxygen.
more information about this is available in the Oxygen Help under
