Can anyone explain me what can be the reason that a simple pr_rop()
operation on a memory pixrect (just to clear it):

  pr_rop(mem_pr,x,y,x_size,y_size,PIX_CLR,NULLPR,0,0);

does not return (it hangs...)  Is it of importance that (x,y) != (0,0) ?
Please, reply by e-mail as I don't usually read this newsgroup.  Thanks!

Dario.
