Okay to re-read?
A confirmation message. To proceed, Viewer will now re-read the disk file. This will affect any alterations you've already made to the display. You may wish to save first and then try again later.
Also, Viewer will try to read the whole text file (up to the limit of 16,368 sentences). If you have a very big file on a slow CD-ROM drive, this will take some time.
