You can,
but this bug, I think that it is present from the version 3 or 5,
and therefore the MS should know it.

Fixed ?
I think of no.
I think that the code of the pageframe is not the best possible,
and the Team tries to touch him/it the less possible.
Besides seem me to always perceive a certain reluctance,
to touch the events.
