This doesn't always happen, but when it does, it is very frustrating.  For example,  I open Michael 4 and start creating my own character.  I click on head.  The column on the right lists the dials.  I want to change his nostrils.  But I can't get to the bottom of the column!  It won't go any further down than Nose Bridge Width.  I can't create the character!   Why does this happen and how can I overcome it?   All suggestions are appreciated!
