Non modal form closes with modal form when it is closed

I have a non modal user form that is always displayed. there are many times when I load Modal forms atop the non modal form. but when I close the modal form, the non modal form closes with it. is there anyway around this? I know I can hide the modal form, but I'm not sure I want to simply hide all the user forms. wouldn't they always be then loaded into memory and slow things down?
