        mswapbuffers

                Not supported.

                Swapping multiple windows (e.g. main and overlay
                buffers, or windows on separate displays) can be
                accomplished with multiple calls to
                though this involves a race condition.

works OK :-), if not :-(
I'll see if I can find any more info.

Cheers
Rob
