When I make my changes in the editor then click commit, the screen goes blank and a colored box show up in the background layer. I have used this program for years and this has never occurred. I am not able to save my editing.
This is weird. Try resetting editor preferences. This would probably fix your problem if it was working fine earlier.
1. Close Elements.
2. Launch the Photoshop Elements Welcome Screen and hold down ctrl + alt + shift as you click Editor.
3. Continue to hold the keys until you see a message box asking if you want to delete Photoshop Elements settings file; click Yes. Elements will open with default preferences.
