i've rechecked the change about 10 times now to ensure there were no errors or mispellings, etc., and it simply is not working. dreamweaver leaves all the code black. none of the php is using the color. why would that happen? is there additional considerations? do i need to clear out a cache of dreamweaver? these are the directions that is generally accepted as how to add an extension, and its simply not working. shouldn't matter, but i'm using dreamweaver cs4 on osx.
