thanks. It sounds as if you may find a page that just happens to hit the margin at some place that triggers the problem. So screensize matters.

Now that you mention screensize, I can reproduce it resizing the screen, but resizing back to what 'resize' reported doesn't fix it.

Looking again at your screenshot, I see that xterm's running without an app-defaults file. That makes it fall into one of the holes in its layout because the form widget gets confused about the size of the vt100 window when it's narrower than the toolbar (something I'd like to fix - different bug list).

Yes, it's because I uninstalled the old from /usr/X11R6 and installed the new in /usr/local. I'll fix this. But it also happens in a console and other X terminals.

ok. In #208 I'll have (have done already) some changes to allow the configure script to put the app-defaults file in the right place.
That'll probably be late this week (right now I have vile, cdk, lynx
on my to-do list).  It's only very recent that more than a handful of
people have used the configure script for installing...

Note that the actual width probably is less than 80 columns. You can check this by spawning a shell from lynx and typing "resize". It looks like 79 columns here.

Spawning your default shell.  Use 'exit' to return to Lynx.

pervalidus:~$ resize

Running from screen it returns 23 lines, from the console 25, and from screen on the console 24. Should it always return 25?

no.  The default xterm size is 24x80 (because that's what vt100's are).
The toolbar configuration has a couple of problems with layout:

        One is related to what I thought I saw on your screenshot (initial
        layout, or resizing makes the vt100 window shrink - I don't
        entirely understand that, though I've studied it).

        The other is that the number of lines is sometimes 23 (that's
        because the height of the toolbar is estimated and adjusted, but
        the adjustment may take away a row of the vt100 since the
        Xaw layout widget is not smart enough).
