Either side can end the iPartner session by clicking the Disconnect button. When you disconnect, iPartner will ask if you wish to synchronize your document with the document that has been edited by your partner. If you select Yes, it overwrites the copy of the document you currently have open in your program with the edited changes in your partner's program. If you choose No, then the document in your program will not reflect any of the changes made since you sent the document to your partner.
