I can't really answer this because I have never seen a message
complaining about the filling of a "buffer". I did see "unable to
allocate memory" a lot, and there is some advice from a very trustworthy
source here:
http://spot.colorado.edu/~romashki/idl/mac_memory_1.html
I found that I am a lot better off trusting IDL to do dynamic memory
allocation on Mac OS Classic than allocating a large chunk of RAM to IDL
manually. I have 1.5 gig of RAM too, but manually allocate only 32 Kb to
IDL. Of course, the very first time I load anything in, IDL grabs more
memory (the max I had it grab in my working routine was 800 Mb), but in
the process of releasing temporary arrays IDL also eliminates the fragmentation.
If you allocate 1 Gb to IDL manually, it becomes internally fragmented
with some small persistent variables allocated in the midst of that Gb
(at least this is what I think) and then IDL becomes unable to allocate
a large chunk (despite having a full Gb) because RAM as to be contiguous.
Hope this helps,
Pavel

thanks for the advice - funny thing, i thought i had gone deep enough
into the rsi folder and found the idl app, to up its memory partition,
but it was actually only yet another alias.... my stupidity.

yeah, i have loved GC for years. the difficulty in this case is that
the TIFFs are 16 bit, and while GC has changed how it deals with that
recently, it still does not deal with the 16bit TIFFs very well. I am
in the beta program for GC, and will be asking Thorsten to work on it,
but havn't gotten around to it yet.
Anyway, thanks for the advice - it worked.

Two possibilities:
1) Make sure your memory allocation for IDL is set as large as possible.
It is still an OS 9 app. (Find the IDL app. Do Get Info. Set Preferred
and Max memory to say, 1 GB.)
2) Use GraphicConverter (excellent sharewhare, OS X compatible) to
convert the TIFFs to a QuickTime movie. View with Quicktime.
