fungus on scanner glasses <!?!>

[Fourtoes]

I have the same scanner an there is an area about the size of a penny with some sort of fungal? growth under the glass....would also like to find out how easy it is to get at it to clean.

i found this, looks quite easy: http://www.carlmcmillan.com/Cannon9950/Canon9950.htm

but now i have another problem, my mac doesn't recognize the scanner. i use mac os 10.6.8 on a new macbook pro.
do you know if there is a solution? i tried the drivers on the cd and on canon's web, didn't work.

thanks!
