[Logic] Info box display problem and workaround

[Bill VanAlstyne]

I noticed right away after installing LOGic 6 that the characters in the
Info box looked really funky -- like there were too many pixels in them,
very hunky and distorted. But they were still readable, so I put up with it
for a while.

Then I observed recently -- accidentally -- that if I clicked inside the
Info box, the characters would clear up, but then gradually deteriorate
again over the next several seconds. This was such an odd phenomenon that I
decided to investigate further.

I discovered that the deterioration of the characters occurs every second,
when the time fields are updated. Somehow, the clock update seems to cause
all the characters in the Info box to be redrawn as an overlay, but not on
exactly the same coordinates. (Or the coordinates get rounded differently
each time. I don't pretend to know exactly how or why this is happening.)
Anyway, as a result of whatever process is going on here, the non-clock
characters degrade over a period of four to five subsequent clock updates,
at which point they reach "max degradation" and don't get any worse.

One caveat here -- it's entirely possible that this problem is peculiar to
my particular video card, video driver, screen resolution, etc. So if you've
never seen it, don't worry about it and ignore this posting.

But if you have the same problem I did, you can probably solve it by
changing the default font (Arial 9pt Bold) to something else. A number of
different fonts manifest the same problem, but some don't seem to. After
some experimentation, I changed my Info screen to use System 10pt Bold. The
typeface is easy to read, it's bigger, and it doesn't get corrupted by the
clock updates.
