This worked, thanks!

object-debugger was removed from v360, now (lib "draw-sig.ss" "help")  
is colored in green.

I pressed "Check Syntax" after uninstalling object-debugger, and the  
red color came back.

I reinstalled object-debugger (in v360), the startup error returned,  
the color of (lib "draw-sig.ss" "help") was green until I pressed  
"Check Syntax" again again, then the color turned red.

This tells me Robby Findler explained the cause of the red color.

I uninstalled object-debugger again (until v369), since I'm getting  
good practice with planet [ -i | -e ] ...
