Hi Ed,
I've been using tiles for several months. Yes, it is a little buggy, buts so far nothing major. Perhaps the most annoying is that every so often it just "loses" a link to a file. Another annoyance is that I can't usually drag the top bar titles more than one at a time (making a liar of me right now tho!). I'm on Win 7, and can't imagine why MS hasn't set up such a user-friendly device in Win 7. Anyway, I find the program of such value I'm keeping it despite its idiosynchracies.
Having said that, it may be partially due to the fact I've never really studied up on the Win 7 "Libraries" thing, which to me is a nuisance, blurring the distinction between my true directory paths and something else.
If there was a feature I could have added, it would be to be able to save an open file to its file tile, or its folder tile on the Stardock bar.
Cheers,
Keith
