I hope someone can help me with a problem that just developed while entering my sources to PAF. I have a very lengthy source that I got about half of the actual text input when the program suddenly would accept no more information -- until I exited and clicked on "Edit" to open it back up again. Then PAF allows me to type a few more characters and quits again. I have to exit, then edit again. Over and over and over. Does anybody know why this happens and how do I solve this most frustrating situation? Thank you for your help.
