IE8 fully exploited the issue. The other (good) browsers and other versions of IE exhibited the issue, too, but it was so slight that it was virtually unnoticeable. In fact, until it was fixed I didn't even realize there was a problem at all with the other browsers/IE versions, but could perceptively see the improvement afterward. Anyway, since it stuck out like a sore thumb in IE8, that led me to believe that it was one of the dreaded known IE8+CSS issues when floating elements. There are work-arounds, and I was down to the last trick in the book, which was the most aggressive work-around and required additional styles in tipsy-social-icons.css and a class in the markup in tipsy-social-icons-content.php. Not knowing how much code I'd have to sift through to find the place I wanted to add the class, I was ready to search on ".tipsy-social-icons," but was surprised to see very little code and I was able to scan through quite quickly and the discrepancy jump out right away. Only reason it took me 4-5 hours to figure out is because I really thought it was an IE8 issue all along (and, boy-oh-boy, I was cussin' out IE the whole time!), not a plugin issue, so was focused on a bug work-around that wasn't really there <heh>. #canibuyavowel? ;-) #sorrymicrosoft #iestillsucks!
