Macro sometimes runs and sometimes doesn't

[tmurphy127]

I developed a simple set of macros that insert already made files into the
current document.

Sometimes the macros run and sometimes they don't. All are located in
normal.dot.

If I "manually" insert one of the files (File/Insert/File), sometimes the
macros will run subsequently, but not always.

I can't discern any consistent pattern. Any thoughts or suggestions?
