I have had V5 and V6Inf and never had a problem getting the camera to rotate.  Yaw, pitch and roll all worked for me.  But now in V7Xstr I cannot get the camera to rotate along the Z (roll) axis.  The yaw and pitch work just fine, but the roll function is just not functioning.  I am sure there is a setting I am overlooking but for the life of me I cannot find it.

Anyone have any tips or having the same trouble?  Try it and see for yourselves.
