Hello, I recently upgraded to Mac OS 10.3.4 from 10.3.3. After the upgrade my scanner drives no longer registered in Photoshop. I eventually downloaded Epson 10.3.3 drivers and using Image Ready I was able to get the TWAIN aplication to respond and scans complete. I also started having problems with my Flash Drive. I started receiving "drive is full" messages during drag and drop copy operations, even though "get info" reported hundreds of megabytes of disk space available. Disk Utility would not erase the disk giving me an unmount error. I finally was able to partition the disk but the same disk full errors occured. The flash drive was in MS_DOS format for PC compatibility. I eventually partitioned the drive under Jaguar. Are these known problems? Is 10.3.4 stable? Is the solution to re-install Panther from scratch and then only upgrade to 10.3.3? John F. Richardson
