Following-up on Ashley's links:

I have removed all foreign-language files from the "Legal" folder which is installed with all Adobe applications.

I do all scanning from outside Photoshop and have disabled the CS2 TWAIN plug-in by putting a ~ (tilde) in front of its name.

I use NikonScan 4 and SilverFast Ai scanning software (but never Silverfast SE, Epson or VueScan).
