Possible problem here:  HyperTalk's file read and write code has a (memory here,
don't quote my numbers) 16k file buffer size.  If you are attempting to skip
over existing text, this MAY not work when the file has more than 16k in it.

In other words, "read from xx until yy" really means "read from xx until yy
OR 16k of text read in".

This factoid presented to you from memory.  Please test before believing me.
