I'll have to check out this tablet program, but try RealVNC's PPC client. It's the best VNC program I've found for the phone. You'll need to install a VNC server on your PC, but I also like RealVNC's PC server the best too. they're both free. Since you can install VNC as a service, and not just a program - it will launch with the PC before the windows login.
