Custom color themes can't be edited after creation

Description of your problem

What steps will reproduce the problem?

1. Open Preferences
2. Create a custom color syntax theme – save it – close the dialog window
3. Click ‘Edit selected’, change one on the colors, click OK

What is the expected output? What do you see instead?

Clicking OK does NOT save the edited color. Furthermore, clicking OK closes both the color scheme creation window AND the preference pane.

I don’t know if this is the same problem, but I cannot make ANY changes to themes or to a newly create theme. Any attempt to change the any of pre-defined, or even the default settings when creating a new one, no changes are saved.

In effect, I can only use pre-defined themes.

Thank god for this post! I had the exact same error. Im on a laptop, no screen real-estate left so after clicking ‘ok’ the preferences window went to the background of spyder, instead of staying on the front of the editor.
