sametime module in stable release

Hi all,

I've worked with tablix for some years, but every time I've had to
change the source code of the module sametime.c, because it doesn't work
as I expect. I must comment the next line in grade_function:

if (t->inf[c].room!=t->inf[b].room)

If I leave this line the result gives duplicate teacher-class pairs at
the same time. So I don't understant why that comparison in the rooms
must be made.

Is anyone getting this same problem?

I attach the xml config file. You can see that if you comment that line
the result is perfect, otherwise you get tuples at the same time.

Thanks in advance.
