I think this is a known issue.  Sometimes events get out of sync somehow,
i.e. the draws to the screen don't happen after the corresponding keypress
but rather are delayed until the following keypress.  I don't know if that
is what you're seeing here (I'll test this some more tonight).

Yes, this one I'm still working on.  I need to know what's changed on the
screen so I can avoid redrawing the whole thing.  xt5250 doesn't flicker
because curses doesn't redraw the whole screen at once, despite the fact
that the whole screen is redrawn (curses_terminal_update() redraws every
character on the screen regardless if it is different).  I need to think
some more.

This "extra" space is there on purpose.  The field underline takes up one
pixel, and there is one pixel on either side of the underline.  This makes
it so underscores aren't hidden by the field underline.

Yup, fonts.  The font can be selected using the standard X argument -fn
<font name> or you can specify it in .Xdefaults.  The X5250 resource file
included with the source has all the customizable user resources in it.
Also, x5250 --help shows a list of commandline arguments.

I had forgotten about the .tn5250rc font_80 and font_132 arguments.  I'll
add those in.

There is, I added it just for you!  x5250 -pastecursor (or -pc) will
revert to the xt5250 behaviour.  And there is a user resource for this,
too.  See the X5250 resource file.

This I haven't figured out yet.  I think it has to do with the X selection
atom type, but it may be that OOo and moz want to work with cut buffers
instead of the X selection mechanism.  I've gone over the xterm code to
see if I can find out how xterm does it, but haven't had any luck yet.

It doesn't always crash for me.  The time I have problems is when there
are multiple windows on the screen in the same position.  I think the same
thing happens with +enhanced and xt5250 as well.  As you know, the
enhanced 5250 protocol isn't ready yet when it comes to windows (I'm
hoping to hear back from the tn5250j guys on this).  Does it crash for you
on every window?

Thanks a ton for looking at this and reporting the problems!  Feedback is
always great.
