20010226: 20010226: 20010222: No permission to write VG file


If the pallete pops up with all black buttons, then it cant get the color
for the background. That isn't one of the colors allocated in advance by ntl.
Its an X thing. probably need to close something- or start ntl with less colors.

If some can save and some can't save, then it sounds like something
is different in the setup, such as the uid user id.

Looks like the only way to figure this out is to see why the routine
is returning a cant_write status. I'll compile a version of nmap2
with lots of output statements in the routine to see what test is failing.
