This is in reference to the xdvi in the sipb locker.
If I remove a .dvi file and then recreate it, xdvi does not read
the new file. Instead forcing a redisplay simply redisplays the
contents of the old dvi file before it was removed.
Xdvi should be able to detect this case. I haven't looked at
the code, but I would guess that it is probably failing to check
certain error returns from some calls. If it sees that the dvi
file is newer than it was when last read but it cannot read from
it, it should close and reopen the file.
To reproduce, run tex/latex over a file, xdvi it, remove the dvi
file, change the tex file, rerun tex/latex, and then try to
refresh xdvi.
