I just released VueScan 6.6.4 for Windows, Mac OS and Linux. It can be downloaded from: http://www.hamrick.com/vsm.html What's new in version 6.6.4 * Fixed problem with some very dark negatives * Fixed problem with Agfa Arcus and other Acer-manufactured scanners not being recognized occasionally * Increased exposure time for long exposure on Minolta Scan Dual, Scan Speed, Scan Elite and Scan Multi. * Fixed some rare problems with cleaning images * Fixed problem with eject after scan with Scan Dual II Regards, Ed Hamrick
