Howdy,

Some more notes on this.

One should let TeXShop search through the complete file to set up  
syntax coloring; that takes a while with a large file and exaggerates  
the slowness.

Once syntax coloring is complete for the entire file there is still a  
fairly dramatic slow response time if line numbering is turned on. If  
you turn line numbering off there is then a dramatic speed increase to  
normal levels.

Dick, if you want to have me take samples, etc., please let me know.

Good Luck,

Herb Schulz
