You could've identified part of the cause, Jim (it is XP). I've got auto updates turned on for the machine in question (probably not a good idea......).
I've got SP3, and also received a bunch of security updates on the 12th June, a few days after that I downloaded the new version of PowerSDR and noticed the problem. As it happens, I've been poking around this machine to try and find the cause, and the latency problem disappeared when I stopped Norton Internet Security. As you might expect, it didn't re-appear when I re-started it. Norton had been running on this machine since I first configured it. So, now the problem is to try to make it happen again.......

Are you using XP? and if so, have you picked up a few updates in the last couple of weeks? I have declined to install SP3 because of a number of cautions here and there, and I didn't really feel I had any problems, etc. However, I got stupid a week or so ago and selected a bunch of potentially needed updates. CPU usage went to 50% of total on AMD 64X2 4600 machine. Gave up finding the cause, removed updates with restore via Norton Ghost (windows restore back to before updates DID NOT remove the updates)! System back to running like a thief in the dark!
