I don't mind posting a short bunch of code to the list, but a compiled applicatin wouldn't be popular. You really, really, REALLY ought to move to FB3. I have FB2 and FB3 side by side on my machine with no problems.

No, you missed the point. The Edit Field will hold a contiguous lump of text. As you move the scroll bar, the program will grab chunks from the container (another reason to use FB3) and add them to to beginning or end of the EF. The user won't know it's happening. He (or she) should just see a big text file scrolling. One document, one edit field. Phil.
