I just compiled the source with the latest snapshot, and now it looks
like this:

  http://www.cling.gu.se/~cl3polof/simple285.png

No code changes yet, just a straight recompile. It redraws the menu
correctly when I move around with the cursor,

        DrawItem(item, menu->xpos + 1, menu->ypos + menu->current + 3, 0);
        item = item->next;
        ++(menu->current);
        DrawItem(item, menu->xpos + 1, menu->ypos + menu->current + 3, 1);

but not when it's initially drawn:

        item = menu->firstitem;
        while (item) {
          DrawItem(item, menu->xpos + 1, menu->ypos + l + 3, menu->current == l ? 1 : 0);
          item = item->next;
          ++l;
        }

Adding

        gotoxy(0,l);
        cprintf("x: %d, y: %d\r\n", menu->xpos, menu->ypos);

before DrawItem changes the position (x correct, y off by 2).

Any ideas?
