This problem (and others, see later) was due to a bug in the 3.02 Lattice C 
compiler.  Lattice C 3.03 fixes this (the icon is kind of a cute little
mandelbrot) andfixes  also the following problems in the mandelbrot code:

- sequentail assignements to floats (fixes where previously givem on the net)

- quitting to go back to the workbench (previously if one executed the mand
program from the workbench, Q(uitting) would lock the machine).

The following problems are still to be fixed:

- when executing Analize, one gets stuck and Exit from that screen does not
work. One has to reboot.

- when creating a 640x400 high-res image (mode 7), the image is created
correctly, but when one tries to invoke a menu the machine crashes with an
"out of Memory error" and Guru Meditation #04010003.4C500000
