PROBLEM: (82695, 83772, 83624) (PATCH ID: OSF440DX-023)
********
   The default MIME types are not defined in the Netscape Communicator 
4.75 web browser. The result of this defect is the web browser will process 
some file types in an incorrect way. For example, a file with the
filename extension .HTM that normally might match the HyperText Document
MIME type, may not get displayed in the web browser as an HTML document, 
but instead, may be displayed as a TEXT document. Whether or not this 
problem actually occurs depends on the contents of the file.
   This patch corrects the problem by upgrading the Netscape Communicator
4.75 web browser to Netscape Communicator 4.76. This version of Netscape
Communicator has the correct default MIME types defined.
