Hi all,

I have been keeping up with the list lately, but just haven't been doing
anything with Imagine recently, so I have been keeping awful quiet.  However,
I have seen this problem mentioned before, and have always wondered if it
might be something similar to problems I had way back with image mapping
in Turbo Silver.  I have not checked this out at all, but I just thought
I would throw it out and let someone see if this might help.

I remember getting black seams along the right side of a brush map if the
brush's width was not a multiple of 8 (maybe 16, I forget exactly).  Again, 
this was from a early version of Turbo Silver and I even saw the problem
with non-repeating maps.  But I believe I saw similar problems using 
repeatable maps in the early days of Imagine also.  So, if anyone is
willing, you might try scaling your brushmap so it has a width divisible by
8 or 16 before trying to map it using Imagine.  I can't imagine that this
is really the problem, but I don't suppose it would take long to experiment
with this (and I've always wondered about this strange bug).

Well, now that 3.0 is shipping and I recently spent some money to buy a
3000 (the OLD 2000 was giving up the ghost part by part), maybe I'll get
interested in doing some more rendering on my Amiga.  It's been a long
time since I have had the patience to render some animations, but I think
I'm getting the bug again.  Thanks for all of you that are keeping us
up to date on your experiences with 3.0!!
