Please write a bit more of what you did: was `watchfile'
active, or did you click on the window, or didn't you do
anything after the `xdvi: File corrupted, not reloading.'
message?

Sorry. I often work so fast that it's hard to remember what
exactly I did.

I have watchfile active. I guess, I corrected the tex file,
restarted latex and clicked xdvi to bring it on top.

Let's see if it still happens with 22.84.4-CVS1? (I closed
#873746 and #876753 since i think they have been fixed by
the change, maybe this one is related too).

Actually, this was a different bug, which should be fixed
now in 22.84.5-CVS4.

The reason was a read_events() call in load_font() which was
supposed to update the `creating fonts ...' popup, but which
caused a recursive call to the file loading code when user
clicked on window, thus messing up the m_dvi_fp (bloody
static variables!).
