First I want to say this is just a small bug and doesn't need immediate fixing. It's just a small annoyance.
Copying or Pasting in Color Selection doesn't work at all. Using CTRL+C or CTRL+V doesn't work. But it works when I right click and choose Copy/Paste.
Step-by-step:
1) Press C to open Color Selection screen.
2) Try to Copy or Paste any of the values by using CTRL+C or CTRL+V. Nothing happens.
3) Try to highlight the value and right click and choose Copy and then Paste. It works.
Anyway, thanks for the program and keep up the good work.
