Turn off conflicting software/clear memory

  • Restart the software (Fireworks, Photoshop, etc.).
  • Restart your computer
  • Turn off any Macro products you might be running

Reset your preferences — Ah -ha!

  • Edit>Preferences>Reset all warning dialogs (Photoshop)
  • Edit>Preferences (Fireworks; save — I didn’t reset my preferences, just re-saved the existing ones and it worked)
  • Commands>Reset Warning Dialogs (Fireworks)
