Hi John,

I had to re-download OSLO-LT the other day because I lost it when my 'puter
crashed. I got version 6.1 this time. Playing with it, I noticed a few very
minor differences. I've noticed there's a few things I like about Beam 3
more than OSLO-LT. One thing, when working with off-axis stuff Beam 3 is
more intuitive to me, and returns results that I can understand right away.
Another thing is the graphics window, when you're looking at a diagram of
the system. With OSLO-LT you can use the mouse to drag a box for more
magnification, but the amount of available magnification is very limited.
With Beam 3 the magnification seems unlimited. At least, I know I've zoomed
WAY in, and I don't recall hitting a limit. And that's the way vector
graphics should work. And Beam 3 always has nice scale bars sitting there.
Maybe if I ever have time to really learn how to work OSLO-LT I'll be okay.
It's capabilities certainly far exceed Beam 3, and it was $300 cheaper. So a
big thank you to the folks at Sinclair/Lambda Research.


John
