Are you sure you aren't using Desqview or Windows? I have had the problem
there (only). I haven't found a cure, but I do offer the following
horrible kludge: your cursor will reappear when you move it.

ibmmove(row, col)
{
        rg.h.ah = 1;            /* set cursor size function code */
        rg.x.cx = 0x0407;       /* turn cursor on code */
        int86(0x10, &rg, &rg);

        rg.h.ah = 2;            /* set cursor position function code */
        rg.h.dl = col;
        rg.h.dh = row;
        rg.h.bh = 0;            /* set screen page number */
        int86(0x10, &rg, &rg);
}
This is in ibmpc.c
