Though not specific to Dave's question, the apostrophe seems to be the most incorrectly-used punctuation mark in written text. Errors are rampant when referring to plurality of words: photos(NOT photo's); FBOs(NOT FBO's); and uncountable other incorrect applications when only plural reference is indicated, NOT a possessive factor.
Also, the it's(correct when "it is" shall be inferred) and its(when possession is stressed) are, without a doubt, the most common transgression in written documents.
And noting that Dave correctly applied It's(above).
There! Rant over. Happy Sunday, everyone.

[EDIT] I don't know how to answer your question, Dave. The problem has something to do with programming in software. I know nothing about that but Jesse, or other IT folks, can probably answer your question.
