Re: Tracker Files field creating duplicate uploads
I know that they were different tracker plugins, but I figured they probably shared some functions, and they all get executed each time the page generates. Plugins often pass data using session variables and if two plugins accessed the same session variable, there could be some problems. But your testing with just the one tracker plugin appears to have ruled that out.
I did some searching on IE10 and "File Selection" and there are others that are having problems with file selection, but I don't find any mentioning getting duplicate files. Have you tried using the browser compatibility option to see if it you still get duplicates?
