OK, here's the story so far:

Occasionally my ST Color Monitor SC1224 fills up with vericle lines along
the left side of every other character column.  In lo rez that means 20
verticle lines, in med rez it's 40. 

But this only occurs in text areas.  If I boot from my hard drive using ICD's
host adapter, the screen's starts out ok but once the GEM desktop appears so
do the annoying lines.  Then my desktop picture arrives covering up the
lines.  The picture looks fine except for some traces of the lines on the
picture's extream borders.  Then when the drive windows open up, the verticle
lines are back, but now only on the inside of the drive boxes.

At first I thought it might be anything from loose connections, to my
monitor master (although I am currently sans Monochrome - got one to sell?),
to a hard drive virus (yeeeks!).  So I turned everything off for 5+ minutes,
disconnected my hard drive, connected the Color monitor directly into my
Mega4, and booted with a virus free disk.  Sure enough, the same problem.

Essentially, where ever text is or can be displayed (including editable text
fields) are verticle lines on every other character's left side.  This includes
the space character.  Some times these lines preclude the character entirely
and I end up with lines like:


| | | | | | | | | | | | | | | | | | | | | | | | | |
| | | | | |l|c| |e|e|t| |o|t|n|e|)| | | | | | | | |
| | | | | | | | | | | | | | | | | | | | | | | | | |

It's happened three times in as many days for seemingly random reasons
and lasts anywhere from a few minutes to an hour or more.  The first time
I recall this happening was during a large hard disk to hard disk copy.
The size was about 4 megs of information, with <300 files and folders.
(Yes I have plenty of extra folders allocated (2500) thru ICD's software.)
During the middle of copying and updating, the copy window ( `currently
copying filename to filename') gets the lines.   Another time was on
returning to the desktop from an application (application name forgotten).

No amout of re-booting, jostling of cables, or praying to local deities helps
what so-ever.

Any clues?

Thanks in advance.
