I've finally got around to trying Salling Clicker again and it is impressive!
I recommissioned an old laptop (4 yr old Core 2 Dell with 1GB RAM!) using Windows 7 and Media Monkey, reading from my main PC in the study over WiFi (ethernet socket is faulty on laptop!). Installed Salling, downloaded the MediaMonkey script, then downloaded the beta Windows 5/6 mobile client to the HD2, and all worked from the word go.
I can now control my music from anywhere in the house as long as the HiFi is turned on

Who needs a Sonus Music Player!
