I installed dosfstools.rpm (fc7, as this is what the site says for Fedora 8; no fc8 version) for vfat format, ran gparted, modified a partition size and formatted a USB with FAT32. All went fine, but after half an hour suddenly the Thunar showed weird behavior. I closed the AA1 and restarted. It went blank, with only a big X as the mouse pointer. All black. Any ideas? I tried to reinstall using the fc10 (dosfstools-3.0.0-2.fc10.i386.rpm) but I felt some problem with Thunar. So I uninstalled it.
