Re I have several global variables that I pass back and forth between the sub's. ... the sub would modify the global var and the other subs could read it just fine

What do you mean by "pass back and forth" there? If each sub just accessed the global, you're not passing anything. If you are "passing" something too, maybe you're getting something mixed up.

You need to post an example of what you are doing. If that is indeed odd, we'll be able to tell.

Oh, and make sure you use strict and use warnings.
