Fixes: - If the units of a User Defined scan size are changed from cm to pixels, and then back to cm, the resulting User Defined scan size will be slightly different than the starting User Defined scan size. - The Scan Configuration Size setting defaults to Letter, not A4, when the region is "United Kingdom". - Using TWAIN via Acrobat 9.2 might cause the application to unexpectedly quit. - General problems affecting the use of the TWAIN driver with the Mac OS Preview application. - All characters in the names of "Save Scan Configuration" profiles are converted to upper-case. - Use of the TWAIN driver setting "Scan Configuration Mode Grayscale/Black and White" with Adobe Acrobat's "Color/Grayscale Lossless" function results in images that are distorted. - The preview screen is always blank if using a fresh installation of the TWAIN driver (not one that has been upgraded from an older version). Please do not forget to check with our site as often as possible in order to stay updated on the latest drivers, software and games. Note: Try to set a system restore point before installing a device driver. It will help you restore system if installed driver not complete.
