Editing turns to custard when copying selected text to clipboard with
^C while working over a slow (128kbit) link. Reaction times to
anything are many seconds from then on. The correct state is
unrecoverable and the nedit server process must be killed, forcing a
complete restart of all open windows. The clipboard is unusable.

SuSE Linux 8.1 ix86, kernel 2.4.19, nedit 5.3, openmotif 2.2.2
(libXm.so.3.0.1), all compiled by SuSE with gcc 3.2. When nedit is
compiled with gcc 2.95.3 and linked static with openmotif
2.1.30MLI4 it's equally bad.

I hope it's not an X error or a motif "feature". Thanks for any
pointers,

    This is a very old bug, and I've seen it myself. One way
    around it is to use middle-mouse button to paste the
    selection, which seems to take no time at all.

    I've never seen NEdit hang completely, it usually takes a
    few seconds to complete the clipboard operation if you're
    patient.

    Thanks. Although is is possible to use the middle-button to
    paste, efficient editing requires both. It also requires having to
    remember when using nedit over the network, and then not
    using some features one is used to using all the time with
    every app. As you say operations complete after several
    seconds - yes, each operation. Move cursor one character -
    wait 5 seconds. Move cursor down - wait 5 seconds. Type
    character - wait 5 seconds. Sorry, this is completely unusable.
    Accidentally typing ctrl-C means restarting nedit from scratch.
    Not acceptable.

    I am becoming disillusioned with nedit due to the large number
    of problems with it which aren't addressed. Most of them due
    to this motif rubbish.

    Another workaround. Over slow links, I've been using
    TightVNC lately, which makes things much faster, and this
    problem does not show up.

    I can confirm this slowness when using Nedit as a remote X11 client.
    Ping round-trip time from host running the X server to host running Nedit is around 50 msec, that doesn't explain the clipboard slowness.

    On my computers, nedit is *sometimes* slow for everything I want to copy
    and paste in / from the clipboard. If I select and use the middle button it's
    also the same. (but it's quite impredicable, sometimes it's correct for
    pasting, though on KDE it seems to be worse)

    NEdit 5.4

    it's running on debian/knoppix linux. I had similar pbs on all the debian built

    One thing I've noticed is "klipper" on KDE 3.2 makes
    everything slow. It was especially terrible in Mozilla.
    Disabling that may help you.

    Try starting xclipboard to recover. Does this work?

    Does using xclipboard changes anything?
