Hallo, World!

Sometimes my simulation program sets monochrom mode after

  GrSetMode(Gr_default_graphics);

The probability of this increases with larger memory allocation
(Statement: You will never have enough memory...)

But sometimes it's Ok -> 640x480x16 colors.

Usage of GR_biggest_graphics 
or Gr_width_height_color_graphics
does not help

Where should I look for solution?

I work under Win95, 133MHz, 32 RAM,...~100Mb free..
mem returns 599Kb free, the size of exe file is 420kB

Maybe I make InitGraph in a wrong way.
A good example could solve all problems I think.
(I have used a piece from ...../grx22/test/test.h)

By the way, I make text output in graph mode by means of printf()
Is it Ok?


Thanks

Eduard
