Startup Problem For Multiple Users

Using W98 2E. We have 3 users on this computer and each one must log
in to their own environment. I feel that something has changed. I am
the only user that uses Quicken. I have set Quicken Billminder to run
on Windows startup. The other users are now telling me that it is also
running when they login. If I go to run msconfig startup and
uncheck Quicken Billminder for any user then it becomes unchecked for
all users and vice versa. Is there a way to keep seperate startup
lists for each user?
Thanks for any and all help.
