Ok, I am still a complete Mac newbie, so yeah, I have no idea what I'm doing. It seems like I post a new question here every week (though I'm a good girl and do a search first!). Thanks for all your help guys! Anyways, I lugged an old AST brand CRT monitor from the basement that we weren't using to have fun with dual displays until I can afford a Cinema. It's been working kind of screwy (i.e. it will stop displaying every now and then and I'll have to disconnect it and reconnect into my PB). I was messing around with wallpapers for the second display and just for fun tried out the "change every 5 seconds" wallpapers on my PB and the second monitor. Needless to say, that got old fast, so I went to change it back to normal; everything went fine on the PB display, but the CRT WON'T stop changing the background! I've unchecked the "change pictures" box on each preference box, set it to a new paper, but then it changes in 5 seconds anyway! Even when I set it to the standard Tiger wallpaper, it still fades into a new wallpaper from the same folder I was using before. It's getting annoying. I've tried restarting, reconnecting, and it still keeps changing the background (but not on the PB display, only the CRT). What's wrong??? Thanks!
