That's true. It's due to something in WATCOM's graphics
library. I can't easily fix it. That's why system() has a second
argument that allows you to restore your original graphics mode
after running a program that might change the mode.

To avoid problems, system("xxx", 0) or system("xxx", 1)
should be used whenever xxx might possibly change the
graphics mode. If you are sure that xxx will not change the
mode then use system("xxx", 2).
