Odd and annoying file dialog behavior

First, I wish to point out that I do not use iTunes at all - have yet to even run the app for the first time on this current install (this problem was also evident on the prior install before I performed a complete erase and install for other reasons).

From time to time when I access the file open or save dialog, instead of pointing to either the last used folder or just my home directory, it will be opened to the iTunes library (and as I said, I have no use for iTunes; the main reason being is I can't hear).

There is no one app for which this happens consistently, so it's hard to describe how to replicate this issue; I just wanted to hear if anyone else has seen this issue and the solution (if one exists). I did ask on this in the past but got only chirping crickets in response.
