[hpsdr] PowerSDR issue running the new Dual Atom processor

[Ronald Cox]

Has anyone else seen this problem running PowerSDR (KD5TFD 22AUG2009  
A) Ozy FX2:20090524, Ozy 16, Mercury 27, Penelope 12, CPU 30.9%,  
Buffer 2048, Sample Rate 192000, OS: Windows XP Home edition, MB: new  
Intel D945GCLF2?

When I do a mouse wheel tune (with mouse wheel tune enabled) one  
rotation click results in no interruption of the panadapter display,  
but more than one click results in a freeze of the display of about  
one second for every extra mouse wheel click, changing frequency by  
dragging the display results in the same effect. I have just updated  
all the intel drivers, changed priorities, hyper-threading, and  
display hardware acceleration with no change in performance.

I have a nearly identical set up: except it is running Windows XP pro,  
on an Intel Core2 Duo (E84000) CPU with a DQ45EK Desktop Board,  
without the problem: PowerSDR (KD5TFD 22AUG2009 A) Ozy FX2:20090524,  
Ozy 16, Mercury 27, Penelope 12, CPU 16.4%, Buffer 2048, Sample Rate  
192000.
