Clip board problems

[Todd and Margo Chester]

Hi All,

   I am using Cent OS 5.1 and XFce 4.4.2

   I love to copy and paste from program to program.

Problem:  if I copy in one program and then close
the program, I loose the text I sent to the clip board.
I have to reopen the first program, recopy to the
clipboard, leave the original program open, paste
to the second program, then close the first.

   It is, how to put it, "annoying", although
not approaching "pain in the neck".

   Is this an XFce thing or a Linux thing?


Many thanks,
