Re: LOGO-L> problems with ver 6.2

[George Mills <mills@softronix.com>]

There is nothing wrong with your machine. 6.2a should eliminate
the problem. But if you decide to use controls in the graphics
screen you will see the behavior you described. The behavior you
described is a function of the performance of your graphics card.
The end result will always be correct but what you see in between
and how fast it does it is a function of your graphics card.
Zoomed mode runs in this mode as well.

When not Zoomed and no controls are in graphics screen MSWLogo
kicks in an optimization (which eliminates the need to do some
redrawing).
