Grouped object are not behaving consistently in terms of how they are selected. If this is supposed to be the classic grouping mechanism then, once grouped, individual objects shouldn't be accessible unless the group is dismantled. In current beta, LE will select the whole group in perspective viewport but selects individual objects in orthographic views. Kind of negates the purpose of grouping.
[Edit]
Moreover the individual objects in a group can be selected in the scene panel and moved thus breaking the alignment with the rest of the group.
