Yes, I'm still on Win 7 64-bit (but my new laptop arrives within weeks!). That said, I've been having issues in Beta 9 and 10 versions with my desktop icons not refreshing or moving to their proper locations. I use Desktop Fences to keep many icons corralled. Since these last 2 beta versions, my icons stay stationary, but the fences shift. The result is it looks like missing icons or blank/transparent areas within the fences.

Meanwhile, thanks for all these improvements!
