[jaws-uk] Re: Jaws and duo corl tehnology

hello Dorothy
My computer has dual core technology, this allows diffrent applications to
be run at the same time without losing proformance, as the two processors
work together to reduce the work load on each other, were as a single micro
proccessor has to take the full work load, which can slow down the computer.

Regards Frank

 Regarding Dual core technology, I have not understood it, but I think
Zoomtext uses it, am not certain, I do know that in the past a friend
downloaded a Demo version of Lunar, and the effect on his Computer was
Disastrous, he had studied the requirements  Demo needed, the right website 
for
Lunar and it was not stated, in fact this was in
2006 and when I last enquired of the  maker  they  still had not published
it on their website, reason was same as 3 years ago"we are hoping to be able
to work with it soon" the kind friend needed Dual Core as he was a designer.
I do not expect Jaws needs it but  am sure others do.Regards Dorothy
