Add object to a group without loosing group properties

[gerbre]

Hi, what is the correct way to add an object to an already existing group in race renderer? When I select the group and the object and press the group button, all settings for the group (and the objects in the group are lost). So this is not an add operation but a delete and create new group operation. Is there a command/button to just add an object to the group without creating a new group?

This hasn't happened to me. What version of RR3 are you using?
