*
* I am using PC-NFS Version 3.0 to connect to an AT&T 3B2 running UNIX
* System V Release 3.2.1. My environment variable TERM is 'vt100'.
*
* I am developing a large application using Curses and have run into
* a problem. I have to output a string to a window, in reverse video
* and then clear this window. But for some reason when the window
* is cleared the row that contains the reverse video character(s)
* and all the rows that follow are cleared (output) in reverse video.
*
* This problem occurs when the last character output is in reverse video.
*
* The problem does not occur, if the last non-blank character output is
* not in reverse video.
*
* The following source file is a small scale version of the problem.
*
* The compile command that I am using is:
* cc $*.c -o $* -lm -lcurses
*
* Please let me know how I can work around this problem, or what I
* am doing wrong.
