I find it very unlikely that there isn't one of all those addons that contain "UIDropdownMenu" , did you do a full text search (searching the contents of each file)?

I can't for the life of me figure out how to do it in Windows 7s own search-function, besides adding .lua files to the list of types to be indexed. I know it was possible in XP, but can't remember offhand how. :P But any editor more advanced than Notepad could probably do it, I use Notepad++ which has this function ("Search in files").

I did a search for "UIDropDownMenu" in my Postal-folder, limiting it to *.lua only. This yielded 121 hits in 5 files. Not saying Postal is the culprit or anything, just one of the addons we both had.
