NEDIT stops copy/paste after long periods of OK

Hello!

I'm running RedHat at work on a PC box and use NEDIT as my main editor under
KDE. I usually have about 20-30 NEDIT processes open. Once in a long periods
of time (the last time was months ago) most (but not all) processes
of NEDIT stop being able to "copy/paste" inside the same document (strangely,
I still can copy from one NEDIT and paste to another). The last time
I had this problem I couldn't get from our IT guys any better solution than
the windows-style "close everything, log out and log in" and I would really
hate to be forced again to do this. Is anyone familiar with such a bug
in NEDIT (or maybe it's the X-win problem?) and knows a solution/workaround?

THANKS IN ADVANCE FOR ANY HELP ! ! !A
