Is there any special software for copy,cut like operations?
One alternative could be Ultracopier
You could try using the cp command at the command line. It's much less likely to hang than the GNOME copy manager.
This might not exactly be gui, but pretty close to graphic user interface. I use mc (midnight commander) for cutting coping and pasting files. It works fine with ftp and ssh and provides a stable interface for a file manager if that tickles your fancy.
mc is available on ubuntu universe repository and can be installed through the command sudo apt-get install mc .
