Mac click and drag

Originally from ticket #9349.

I'm used to triple clicking to get a line and being able to drag it to a new location. Yet with the CrossWorks editor, triple click does not work. One must go past the end of the line and double click. If you try and move it from there it does not work.To move the line to another spot, one must move the cursor back over some text in the line to be able to move the line. Minor annoyance but it does break the rhythm one expects in a Mac text editor.
