I just released VueScan 6.7.4 for Windows, Mac OS and Linux.

(Nikon LS-30 & LS-2000, Minolta Scan Elite, ScanWit 2740S)
* Minolta scanners now overlap processing and the
return of the film carrier to the home position
* Fixed focus problem on some Acer ScanWit scanners
* Fixed problem on Mac OS with memory being held after exit
* Improved image processing speed on Mac OS version
* Fixed user interface problems on Mac OS version
* Removed "Window|All options" and "Window|Fixed positions"
