Upon installation my color pallete shows colors on new sprite created but lately I noticed it doesn't. Please how do I fix this.
You've barely given us enough information to hazzard a guess.
Have you tried 'File/Preferences/Reset dialogs', in case the window has been moved off screen?
If that doesn't work, have you tried re-installing C2?
If still no joy, post a .capx or screenshots showing the problem.
