More specifically, it includes a font list similar to that output by the
*FontCat command. I can't see any point in Organizer's workspace where it
stores this kind of structure so I'd be tempted to rule that application out
for the time being.

Also, I use POPstar and Organizer all day, every day, (this Iyonix is on
24/7 and has been for years). I have never seen the effect which is being
described in this thread. I'm running RO 5.09 in 1280x1024x16M if that
helps. I have sprite backdrops and 128MB RAM.

Might be looking at the contents of any suspect applications' wimpslots (you
can capture them with Zap) and then searching for something along the lines
of "Homerton.Medium.Oblique" so see if you can spot any lists similar to the
*FontCat output.

I'd also check any dynamic areas associated with the applications - maybe
also the "PCI shared memory" area to see if something there from there is
being 'leaked' into other appslots (or the screen memory).
