Last minute information for ChemPen3D version 1.20

Special Considerations for Microsoft Windows 95 Users

ChemPen 3D is a Windows 3.1 program but will install and
run under Windows 95. However:

1. ChemPen 3D does not implement Windows 95 specific features
   such as long filenames or multithreading.

2. ChemPen 3D does not edit the Windows 95 registry. ChemPen CHP
   files must be associated with ChemPen by the user.

3. At the end of installation, under Windows 95 there is a delay
   that can last up to a minute on slower machines and which
   causes the computer to appear locked. Wait for the installation
   to complete as indicated by the Installation successful
   message box.
