formInWindow & Autosaves

I am curious about the form in window and how the autosave method works. If I have a forminwindow running, adding a record for say a contact and half way though create a new record for something else in the main app when I commit the changes will this commit, commit the changes to all unsaved data?

Yes I think so, look here: viewtopic.php?f=1&t=14236#p75086

there is not much difference between showFormInDialog(modal=false) or showFormInWindow((default none modal)
the only big difference is that it is really another window and not a dialog (which is always in front of the main window)
So now you can have windows that are behind the main application window.
