Windows bug :
If you have an old copy of the COMCTL32.DLL in \windows\system (file older than 08/24/96) you must upgrade it to the newest version from Microsoft.
msvctr.dll   The file MSVCRT.DLL may be missing from older Windows 95 installation. You can install it using this file.
riched20.dll 280 Kb This file is requiered to fix the RichEdit line insertion error.
Download this one if you don't have this file in your Windows System directory.
(the file is normally shipped with MS Office 97, MS Internet Explorer 4.0, MS Windows NT 4.0).
Please do not replace an existing file.
If your computer froze when using "Cartes du Ciel" this is most likely due to your graphic card driver. Try to use a standard VGA mode, reduce graphic acceleration or install a new driver version. There is to much different material and I cannot maintain a list of problem specific to each one.
