Hi guys (axel), Hope this list still works (it's quiet here?) Axel, if you need info about overlay, I think I might be of service. For instance, the B_OVERLAY_COUNT hook _does_ serve a purpose, though its not used on R5/dano: The driver is required to report the _number_ of overlay units the hardware has. If I have two, i'll report two. This means two apps can use overlay simultaneously, and two output windows using overlay will be created which are totally independant from each other. BTW: please remember to ask for the hooks after every new mode set... (just like as it is with acceleration hooks) Bye! Rudolf.
