401k paycheck transfer

I've configured a monthly 401k transfer from my paycheck to my 401k
account. This transfer shows up as an expense in the Banking tab under
Analysis and Report. The transfer should not be categorized as an
expense. I have tried to uncheck the 401k category in Options and then
Categories, it works for that session, but it keeps coming back when i
open quicken again.. This is with Quicken 2009 Premier.

Any ideas....

thanks...
