I read all this with great intrest. Not that I pretend I will retain it all but I am very greatful you guys post these explanations. You answer questions I didn't know I had until you presented them!
Greg, Bill, Bruce, Dave & others I have great apreciation for your knowledge & willingness to share.
I have to admit though Bill & now Bruce's post do sometimes take more than one reading to comprehend!
And Bill, you described my sensation exactly when you said Bruce's post made you dizzy! That's exactly how I felt!
