- Fix custom selection colours using a translucent colour being blended through to black or the window background, addressing incorrect colours in the Custom Query view when using selection colours with alpha values and window backgrounds showing through CREATE SYNTAX sheets (Issue #1099)
- Fix crashes when editing certain colours in editor preferences after a window had been closed, due to not unregistering all observers on SPTextView dealloc - Enable "Draws Background" on the main Custom Query view text view, as custom colours were no longer being drawn after a change in r3750
