i use firefox

hopefully things will resolve when dreamscene is official, however long that will be
the only trouble i ever seem to experience from dreamscene is that sometimes it will crash and go blank, maybe a codec issue
seems alot are concerned with cpu usage i noticed when reading comments from user uploads at deskscapes dreams but i havnt found any situation where it causes performance loss.
for instance i ran the game elder scrolls IV oblivion with mods, max settings and benched using fraps with dreamscene on and off and its the same, i think dreamscene is automatically pausing itself when a game is played.
also encoding videos with it on or off while wmp played music didnt seem to notice anything slowing down, hopefully others will realize that before going back to the oldschool habits of shutting processes and the likes down...but then again, i'm testing on higher end hardware for which vista is designed futureproofed for to begin with.
