This is exactly what happens. i have tried it on RH7.1/8.0 Systems or 
Tru64Unix. The response is no better with Irix (6.5). i suspected that it
was the threading problem as mentioned above. Was not very sure abt it,
but cpu usage does kick to 100%.

The alternatives would be could, but something as simple as view should be
great. Something like 'imagesc' as in Matlab, view i think provides that,
and was simple enough, but i guess now somehow it has some threading
problem.

Any alternatives,
