Problem: Wx::AuiNotebook and mousevents

[herbert breunung]

cheers,
i try to connect in the normal way a mous event to a
auinotebook like:

Wx::Event::EVT_LEFT_UP( $notebook, sub {
        my ($tabs, $event) = @_;
        ...

but nothing ever happens even if in the wxwidget sources the code is there to
make such a connection. a bug, a feature i would like to know more.

thanks
