>I was looking for some method of wrting the ACTUAL source lines to a log file, rather than a refrenece to them. Currently, I then have to go back to the source and check out what the actual line does.

That is what loading the coverage log into the coverage profiler does for you. You can see what lines executed and you can see how long each one takes.

It doesn't, however, help you analyze which line executed in what order (except in the raw file as you've noted).

Frankly, I don't have much success with the coverage profiler in this sort of situation. Can you tell us anything about the conditions under which it occurs? Are the textboxes on the form, or on a page in a pageframe? Are they bound to data? Is there any code anywhere that disables/enables them? Are you using a framework?
