If I leave it run eventually it will stop decoding. No telling how long, could be 10 minutes or two hours .Perhaps I should upgrade to Win7!

This is absolute success! I now have the latest PSDR-IQ working successfully with 'Windows 7' and have just had a 20 minute QSO with a fellow near Boston this late evening. He was running 75 watt.. me 1 Watt. The RST exchange was 557 on both ends, though I must admit that KB1CL came up to an 8 or so by the end of the QSO.
I am using the Edirol FA-66 as sound interface. The Win 7 drivers for that were a breeze to install compared with what I recall having to do with Win XP and of course installation of PSDR-IQ was also a piece of cake since the FA-66 is a recognized interface in the PSDR-IQ set-up.
The new computer is an Intel 7i with their Quad 4 CPU running at 2.8 Gigs or so. The latency issues I had with Win XP and the P4 Duo earlier have completely disappeared. I still need to fine tune the PSDR-IQ settings but it was a pleasure already working the station earlier without the drop-outs occurring every few seconds.
The only issue I ran into with Windows 7 was installing the Si570/USB driver. My initial efforts were blocked by Windows' requirement for signed drivers but a bit of Googling taught me that there is means to overcome that. There are programs available to work around that issue permanently but I chose to use the option M$ has already provided. For those not aware.. You press 'F8' while booting up and the 'Safe Mode' screen provides a choice to turn off the signed driver requirement. The status will remain until the system is booted again. I had not problem installing Fred's driver when I used this method and PSDR-IQ suddenly came to life!
I attach a couple of files which show the difference in latency between my former installation with WIN XP PRO and the P4 Duo CPU vs the new system as described above. I think I will enjoy the new system greatly as I learn my way around Win 7. I am kind of happy tha the local vendors talked me into taking that step!
