Hi Hugo,

this is for the 2nd mail :-)

Exactly what we did or do except void MediaPlayer::callbacks() is static... The compiler will not let me do it without.

Exactly the same again.

I´ll try that again.

It seems strange to me as well that mousemovement should cause the error. But it only appears iv the mouse moves...
