I modified vmrun as suggested
the display is very nice but at the end of it the execution window is dead
and no file appears
I have to kill j.exe through the task manager
The file that I run consists only of
load 'viewmat color16'
test_viewmat=:3 : 0
( 1 4 14 {". COLOR16) viewmat i.4 4
savemat_jviewmat_ 'C:\Temp\something.bmp'
)
PS at least I get the display but still no save
cheers

I just started paying attention to this thread. I experimented enough to
verify that the problem is a gl2 bug. This should work as desired and it is
a bug that it doesn't. The bug is unlikely to be fixed until a future
release.
I haven't tried it yet, but David's suggested minor code modification to
viewmat is a plausible workaround for the bug.
