I modified the C51 file-specific options for one file in my Project, and the 3 brown (or are they red?) dots appeared as expected. http://www.keil.com/support/docs/1851.htm I then clicked the 'Defaults' button, which set all the options back to the appropriate defaults but did not remove the 3 brown dots. How can I remove the 3 brown (or red?) dots, which are now lying?
