Hello,

after having read the announcement of the new djgpp version 1.10
I installed it (successfully) and compiled the sample programs
in the SAMPLES directory without errors.
But running programs which use functions from the library
libgr (e.g. in samples\grtask\) causes a strange behavior of my PC.
Instead of drawing the expected pictures it seemed to me that only the
color map was changed and nothing was drawn. At least I wasn't able to
see anything.
The computer didn't crash, however. I could terminate the program by
pressing ^C. But afterwards the screen looked awfully (the Norton commander
appeared not in blue but in yellow...).
So I decided to reboot DOS to get back the original colors.
In the first moment I thought that the library itself or the drivers
were responsible for these problems. But a comparison to the old
version (djgpp 1.08) showed that this could not be possible.
So I tried to replace go32 from version 1.10 with go32 from version
1.08. After having done so all my graphics programs worked fine.

What might be the problem here?
I use a 80386DX with 4MB RAM, DRDOS 6.0 (with EMM386 in V86 mode) and an
ET4000 with Tseng Chips. 

Bye
Holger
