Hi Arnon,

Admittedly, I've never played around with either SetProp() or GetProp(), so I'm not really sure how I'd apply them to solve this problem. In actual production, what I do is use the Is_Run32() function that I wrote to locate the original instance. Since it's available from the download section here, I couldn't include it in the article.
