What steps will reproduce the problem?
1. I tried to change the text color of the buffs.
2. Moving the mouse on the color window freezes the whole interface.
3. The text color is always displayed as black in the configuration window.
4. Acknowledging the changes by clicking on Ok results that the buff display do not change any more.
Already showed buffs bars are not cleared and clicking on another target does not change the buff bars any more.
5. Relogging results in a loss of the buff bar functionality.

I tried to find out what happens. I do not know why the interface is freezing while moving the mouse over the color window but what i found is that the addon does not correctly stores the text color into Quarz.lua.

Faulty Example of Quartz.lua:
                    ["bufftextcolor"] = 0,
                    ["focusanchor"] = "focus",
Working:
                    ["bufftextcolor"] = {
                        nil, -- [1]
                        nil, -- [2]
                        nil, -- [3]
                        1, -- [4]
                    },
                    ["focusanchor"] = "focus",

If i edit the Quartz.lua manually the buffs working again, until i try to save the interface data or try to change the text color.
But the correct color is always display wrong in the configuration window.

Fixed, thanks for the report.
