I'm a molecular biologist by training, and make my living teaching at a community college in south-central PA.

During my post-doctoral studies I began using Mathematica to analyze microarray experiments involving thousands of gene expression values. Today, I am primarily a recreational user of Mathematica, but I do occassionally use it for adding content to the courses I teach.

comment How can I force an installed, user-created palette to automatically evaluate?
You have explained exactly what I was doing wrong! I was confusing the source notebook used to construct the palette with the palette notebook that is actually created upon executing the source notebook. Thank you for the kindness of your reply! That takes care of "gotcha" number 4,387,203. ;)

comment citation insertion from bibtex file does not seem to work
I have had success using a literature database created by JabRef (jabref.sourceforge.net), which uses BibTex. I've been able to get Mathematica V8, 9 & 10 to work with it, under Windows. Even so, the current citation management of Mathematica is very frail and prone to crashing.

comment Can a System symbol spontaneously leak into a Global namespace?
@Simon Woods. Again, thank you. Your comment has brought me back from the brink of insanity. I would like to encourage you to add your comment above as an answer to this question, because it is the first piece of information that has shed light on the problem. I am adding another edit to my post, and would welcome any thoughts you may have, as new questions arise from your information. Finally, what made you think to look in the stylesheet for this suspicious symbol?

@ybeltukox and Simon Woods. Thank you for taking time out of your day to run my code and provide invaluable feedback. Both of you made statements that are beginning to clarify the situation.

comment Can a System symbol spontaneously leak into a Global namespace?
@Stefan R. You are correct. The program produces correct output. My primary concern about the shadow warning is that I can't explain it, and don't want that to interfere with potential future publication of the program.

@Daniel L. and @ Stefan R. I have just sent a minimal example to WRI technical support. The tracking number is -CASE:2211879 if either of you are curious enough to take a look. I appreciate your following this thread. Thank you.

comment Can a System symbol spontaneously leak into a Global namespace?
@DanielLichtblau. <studyname> is a variable to hold user input for calling their experiment something, such as "insulin gene". <graphicoutput> has Column for its Head, but it is just a picture of RNA sequences mapped to a gene. I don't really expect anyone to solve this without seeing the entire program, but as I hope you can understand, I am reticent to publish everything here as I would like to professionally publish this in the future. Do you think it is worth sending to technical support at WRI if I can generate a "minimal" example of the behavior?

@Stefan R. Where could the ParentList symbol be coming from since I never define it? Do you know any information on what the Symbol context of ParentList is? What does Mathematica use it for? Please see 01/08/2015 edits above.

comment Can a System symbol spontaneously leak into a Global namespace?
@rm-rf. The discussion you reference seems to focus on packages, and that is the darn thing about my program. I am not using any packages, and I never define the symbol "ParentList" anywhere, yet Mathematica seems to bleed it from the System namespace to the Global namespace. See 01/08/2015 edits above.

comment Can a System symbol spontaneously leak into a Global namespace?
@rm-rf. I appreciate your stating that you have seen unusual behavior like this as I really question my sanity sometimes when trying to debug code. The shadow warning is not altering my work, per se - that is, I still get the correct results. However, since I am looking to publish this program, I would rather not have to silence a warning and not be able to explain why I need to do that. I hope this doesn't prevent me from publishing. Please see edits above if you are still interested.
