iBooks author cannot save file
I have published three documents prepared with iBooks Author and had never experienced a "file cannot be saved" error. When this happens the only solution is to close the program and lose your work since the last save. Since the problem cannot be predicted, I have resorted to saving frequently and, when the error occurs, taking snapshots of the latest pages so that I can rcreate them (retype text and reinsert photos). Any suggestions for fixing this problem?
