Close picture button in "read-only Infopath displays"doesn´t work

Hi,

I have created a infopath form with few buttons:

2 navigations picture buttons to move between form views. They are OK

1 Save buton which is OK. Save and close the form.

And my problem:

1 Close picture button. This is showed in registration / edit and view "displays" (when clicked in NEW / EDIT / VIEW items buttons). In NEW and EDIT the button closes the form, but in view it doesn't. I suppose it is coded properly otherwise new and edit will not work. And to make it available for view the check "hide picture button in read-only views" is checked. No other codification is done (no other rule, no formating staff....)

Any idea? Is anything missing?

Thank you for your answers
