Features get deleted on file close

Hi,

If I create Oracle features without being connected to the DB I can leave the file and return with all my features still there.

If I'm connected to the database when I close the file I get the message "You have unsaved features... Would you like to post these changes now?". If I say No at this time the features will not be in the file when I return. Not wanting to post them is NOT the same thing as not wanting to have them at all!

Why can't I close the file and return later to continue editing if I'm connected to the DB? 

Regards,

Krister
