runtime warnings

[brownd1978]

I see the following error message in the REve client log running nominal event display:

EveManager.removeElements can't remove child from mother, mother id = ,4462

[sophiemiddleton]

do you see this all the time or on a specific event?

this will be linked to the REveElement 4462 which I think is the TextSelect. Not sure it can be fixed, but I've done some work on this, so let me know if it remains an issue when my latest code is merged
