Commas in file names? Huh.. yes, this could cause all sorts of issues! We'll have to make an allowance for this such that it will not throw off the reading of CSV files. Maybe have MediaLab/DirectRT extract any commas and replace them with periods (or somesuch) when creating the data files. Honestly, I'm surprised Windows even lets you use commas as they are illegal in short file names and they are used as argument delimiters when using command line type stuff. Interesting--glad it's working ok now!
