[AccessD] subform close

...subform hosted on non-linked main form

...command button on subform

DoCmd.Close ...button animates but form doesn't close

...thinking that I'm probably going to have to set the mainform subform 
sourceobject to "" or another object and clean up anything on the open 
subform such as dirty data before I do it.

...anyone done this and have tested code or suggestions?
