Hi guys , I'm new to houdini, just wondering if anyone else is have trouble selecting faces on geometry in houdini for mac? i keep trying various ways to select the faces i want but houdini selects random faces instead, or sometimes none at all, i figured maybe the geometry might be broken, but even with geometry i create in houdini i get the same thing. i've already tried un-installing and re-installing, but i see no change. any advice?
