Hi John, Thanks for your advice. It came to my notice that on copy and paste a selected paragraph of an OpenOffice document containing several pages I could not do it at one time. I have to made copy and paste at several times even closing all other applications. But if I reboot the PC I can reduce the time of copy/paste. So it generated an concept to me whether the clipboard still holding some documents there which took up RAM B.R.
