I haven't been able to get it to see my internal SCSI drives, even though the drivers seem to be there. Adaptec 29160N... DP800/1.5GB RAM.
My Agfa SnapScan 1212u almost works with it... the scan completes, but then Jag re-launches during the export process. My Epson 880i is seen and correctly identified, but with the notation "unsupported printer"... and it means it. No print.
Everything that does work is noticeably faster... and I am very glad to see the return of spring-loaded folders.
