Submit a Dialog window to itself

[JimmieDog]

i want to submit a form in a window dialog( from a window.showModalDialog command) to itself and close the window. it works fine if i give the window a name in the dialog document and set the target of the form to that name
(window.name="blah"
FORM.target = "blah&quot

but!! it works only with IE 5.5 and above
does any one knows any workarounds or solutions?
Thanx
