The colors in Font View have been changed a little, and now could be confusing depending upon what colors one is using to apply to different cells.
In previous versions when one clicked to select a glyph cell, the resulting color was a somewhat darker shade of the cell color. Now it s very close to the same blue that one can use to color cells.
The same thing happens when one has edited a glyph. Upon returning to Font View, the changed glyph cell has that same blue color rather than a darker shade of the cell color.
