I wondered about the 64 bit - not sure if that is the problem so I'll
try to find a machine with 64bit windows to test.

The fact that even when it works it is slow is very discouraging. I'm
working with histology images that are at least 4Gb in size and I need
to be able to zoom in and out using jp2000 - perhaps the advantages of
using the linux box with 32Gb memory will be outweighed by the poor
display time!

Still the fact that it is possible is useful - at least I don't need
to search for another xwindows package!
Thanks,
Anne
