Empty keyword lists restore all keywords in C#

[TheBoxyBear]

When editing the list of C# keywords to highlights, leaving the list empty restores the list to its default value of all keywords of the category when the Options dialog is closed. Putting a single space in the textbox fixes it, but if all categories are set to only a space, one of them is brought back to its default value.

Until this is fixed, a workaround is to set the color of these keywords to RGB 86, 156, 214 (Obtained from a color picker on a screenshot of code with the C# driver disabled)

Can you clarify why you want to set the list of keywords to highlight to an empty list? Are you trying to disable keyword highlighting?
Asking because there are explicit options to disable keyword highlighting globally....
