Titles with topic groups cannot have more than 512,000 topics indexed for
the search index. (TR 1-29, TR 4-11)
The maximum number of windows, panes, and popups that Project Editor allows
you to define is approximately 153 total (windows, panes, and popups
combined). However, the actual Viewer limit is 255 for each type: 255
windows, 255 panes, and 255 popups. If you wish to define more windows,
panes, and popups than Project Editor will allow, edit the .MVP file
without using Project Editor. (README.TXT)
The largest legal value for the NEAR operator in the [SEARCHDLG] section of
the project file is 32,768. (README.TXT)
Section names specified in an MCI [sections] option or section file should
have no more than 40 characters to ensure the section name fits when the
title is viewed on a low-resolution display. (README.TXT)
