!! I followed the steps in the article - downloaded the app from the market and from the web. The only thing that's wrong (at least for me running WIndows 7 64bit Ultimate via VMWare on Macintosh) was that the article says to connect CHARGE ONLY
and when syncing the app with the phone I kept getting an error. So I changed it to HTC SYNC
and worked perfectly.
when it connects with your phone is starts to sync your contacts, calendar, etc - I just X'd out of it and it stopped. You can go into settings and set it to not automatically sync.
Saving screenshots worked great. I'm glad I can now take screenshots even if it's via USB and my "virtual" PC.
