anyone else with these issues? - after using and working with leopard everyday for a while, suddenly files i save onto the desktop don't show up on the desktop. they appear in the finder but nowhere on the desktop. i have to restart to have the files appear back again. - then sometimes it gets stuck on a file or folder where i click on any kind of folder on the desktop or file and it just doesn't want to open. it keeps the same file/ folder highlighted and no matter which file/ folder i click nothing happens. any ideas/ tips? is this bug related to spaces or something?
