1. PSpad recognize highlighter via file extension. What highlighter is used when you open file? Is your file extension in Highlighter extension list (menu settings / Highlighter) Second problem can be, if your file is too big. There is set limit for using highlighter. Go to program settings / Direct edit button and increase value of variable (in bytes) HlUpToSize=xxxxxxx
2. the line difference is shown on the bottom of PSpad window. I suggest you dowload the last build from PSPad developer forum -- <http://forum.pspad.com/read.php?2,56970,56973> PSPad freeware editor http://www.pspad.com
