Newbie having ViVe editing issues

Hello everyone,

My first post here as I did a search and was not able to find an answer. Hope someone can point me in the right direction here.

I am following this videoand all works well, however, when I go into VR mode with my ViVe, I cannot select the floor with the ViVe laser that he instructs us to build or the walls that all use the same box brush. I have no issues selecting basic geometry however so this appears to be a brush specific issue, but I am a total newbie so perhaps I am missing something here.

Much appreciated
