It took a while to work out, but here it is: Skype works fine as long Activesync is not on. In the old machines, AS would kick in and appear in the memory only after you sync'd. Here it comes up automatically, whether you sync or not. In fact, you should see Active sync running in the background virtually always.
Clicking on the memory you'll see its always on, you press stop, and Skype works for 5-10 minutes, until AS turns tiself back on.
Any fixes for this in the registry?
