The core of the program has been totally rewritten. Now GProc-applet does not use libgtop anymore, it's faster and uses less memory. Everyone having trouble with the previous release should update it. RPMs are now available. GProc-applet now works with the public release of Gnome and with the CVS branch too.
Better support was added for the latest version of the GNOME panel. Different layouts were added for the tiny and big panel sizes. The applet is more usable now.
