Other Help Topics :: dsl user login

whenever i try to install an app through the defualt file manager as the super user. It say i have to login a the dsl user. i have tried booting using the dsl secure and having the root and dsl user password show, but what ever words i put it accepts it. i have tried putting in a new user and then reboot, but it ask me for the dsl user instead. what's Wrong?

MyDSL packages must be installed by user DSL. Installing them as root will give ownership of menu file and temp files to root, which will cause problems for user DSL.
