Scanner settings in Acrobat 6.0

[speigel]

Have Acrobat 6.0 and scanning into it with a Canon Lide30. I need to scan documents using Grayscale 100dpi. But every time I use it the default settings are always Black and White 300dpi. Very annoying Does anyone know how to change this, I've tried every setting on the Canon software, but nothing sticks.
Any ideas before I go back to Acrobat 5.0

Have you tried configuring the scanner settings without having any open documents?

many settings in adobe programs are document specific, and won't apply in general unless you adjust the settings with no open docs.
