[SOLVED] Removing Title and Space from Nextgen Slideshow Widget

I'm stuck. I've spent nearly 8 hours reading posts here, at WP, and at Nextgen (which sends me to WP) and seem to be missing some critical piece of understanding to interpret what I am reading.

I have my Nextgen slideshow working perfectly in the left sidebar - - EXCEPT when I leave the Slideshow Widget Title Field blank, it automatically inserts "Slideshow" as the title immediately above the slideshow in the Widget Title style I've specified. If I put just one character into the title I get that one letter displayed in the same place.

I figured out how to change the style of all widget titles using ATO>Style Widgets>Title. Unfortunately that option doesn't give me the effect I want as it impacts all Widget Titles. I only want to suppress the title on this one Widget, not all of them.

I've read about using "CSS inserts" to suppress the title, but can't figure out where I'd put them. I am assuming they'd go at the bottom of the ATO Style.css file or maybe at the end of the Nextgen style .css, but not sure, and not sure if there are any other special issues I should consider. Perhaps I just need to go through a tutorial at the WP site? If so what do you recommend?

Trying to keep this fairly simple and within ATO standards as I want to be able to update without risk of catastrophe or repeating this misery later on.

I am brand new to WP and ATO and have already contributed to both Flynn and Juggledad, so I am hoping I am posting in the right place with the right details. Here is my configuration:

WP version - 3.05
ATO version - 3.6.4
Nextgen Gallery Plugin - 1.7.4
