Hi,

I am using ciao prolog under windows XP. I installed uDrawGraph 3.1.1 and 
I am trying to call it from Ciao Prolog, it runs uDrawGraph but hang and 
does not return to my prolog code.

Note: Ciao Prolog is compatible with old daVinci. I changed the library in 
Ciao to call:
     uDrawGraph -pipe

Example:
In prolog:
m :- exec('uDrawGraph -pipe', Input, Output, Error),
        get_code(O, C),
        get_code(O, C1),
        get_code(O, C2),
        [C,C1]="ok", .....

The above program will run uDrawGraph and get the work ok, but it hangs 
there, (i.e. not returns to my code to continue the rest of the code.

Any help.

Respectively
Omar.
