Thanks Brian - According to the manual: this function was deprecated back in M2 as more general ways are now available. Don't know obviously if that's actually the case. Anyway, I just tested it in the VB editor but obviously I don't want to have to do that every time so... any suggestions where I should stick it? - careful... I'd like to be able to have it completely transparant i.e. both for ref all home and G20,30 etc.
