Nope, the limit in preferences that you refer to applies to file size rather
than physical image dimensions (which is where my problem is cropping up).
Exceeding the file size limit only produces a warning, not an error. Thanks
anyway. :-)
I'll probably enter the apparant dimension limit as a gimp bug as soon as I
get half a chance.

u know under preferences there is a place where the maximum size of a
picture can be set. maybe ur going over what's set in your preferences.

Hmmm,
Ok, here is what seems to be happening: When the size of the vertical
axis
(I didn't test horizontal) exceeds somwhere around 2250 inches, the gimp
dies or locks up. It doesn't seem to matter what the size of the file
is,
and it doesn't matter how many pixels there are.
Using File -> New, both 1024 x 162000 pixels at 72 dpi and 1024 x 450000
pixels at 200 dpi work fine, while both 1024 x 163000 pixels at 72 dpi
and
1024 x 453000 pixels at 200 dpi fail. I have no idea exactly what could
be
causing this, but obviously an overflow or overrun of some type seems
likely.
Any gimp developers out there care to take a look at this? I'm running
1.2.4 under Win 2K. Fred was running under Suse Linux 8.0 I believe.
Thanks in advance,
