It can be a or it might not be. Nobody of the Free Pascal team is actively 
using Dos, but when we checked it worked. However, you are not the first 
one reporting graph problems.

The only thing I can recommend is to download the graph source code and 
debug it to try to find out where it goes wrong. Once we know what causes 
it we might be able to fix it.
