Since the upgrade from 7.10 to 8.04, the Gnome art manager isn't working for me. When I select anything under the Art-->Backgrounds/Desktop themes/Other themes the program only closes the menu and then does nothing. Not a status window downloading thumbnails or any visible signs that the program is doing anything. It doesn't take any more CPU cycles either.
I'm running a Pentium 4 2.8 ghz HP Compaq with XP pro SP2 and Ubuntu 8.04 installed on separate partitions. I have no graphics card or sound card () installed. I'm currently up-to-date with all updates.
