What I am trying to do is lookahead and see it it's a number - if so great! Capture that number (this seems to work). If it's a series of dashes then copy the dashes. What happens now is that if it's not a number, the regex query just merrily skips on to someplace else in the file and grabs that number - sometimes 6 or 8 lines later in the file. And of course this unexpected grab is the wrong data entirely. From there the regex never seems to recover correctly.
