Hi!

I wrote a couple of small routines using the library GRX 2.0,
which was no problem, yet. Only a few thinks do annoy me a little
bit: first, at the end of the program, I usually change back
from graphics to textmode (from 'GR_default_graphics' to
'GR_default_text'). However, when the program stops, all the text
on the screen (including runtime error messages etc.) is cleared. 
This also happens, if I press Ctrl&C while running a program
in 'GR_default_text' (maybe this is NOT the same textmode which
is originally used by DOS?!).
Another little problem is, that when running a program in a 
DOS box under Windows, changing from text to graphics mode always
causes the DOS box to rise to full screen mode. Pressing
Alt&Enter shrinks it back (this happens under Windows as well
as under Win95) and the programm proceeds its execution.
Does anyone of you have an idea how to circumvent these
'effects'? Thanks for any help in advance...

Andreas
