http://forums.opensuse.org – hi, i have installed suse 11.2 i installed first with KDE, i hav problem with "Dolphin" that it doesn't open on first try and sometime i hav to open it 6-7 times then "dolphin" window appear. same is the problem with "ark", the compression utility. when i double click a compressed file, it doesn't open. when i open "ark" seperately, it runs smoothly. so i switched over to GNOME. everything is fine in GNOME except that the animation and effects doesn't run on it. when i click the check box 'use animation', the animation are applied for 2 seconds only then automatically turns off.
