I am using v3.3.  I load three image clips in the Dashboard, assign the first clip(Image A) to Layer 1, the second clip (Image B) to Layer 2 and the third clip (Image C) to Layer 1.  When I click Go above the Layer 1 control in Layers Dashboard, Image A comes up in Layer 1 just like it is suppose to.  When I click on Go above Layer 1 again, Image B come up in Layer 2.  I would think that Image B should only execute if I click on Go above the Layer 2 control.  Is that right?  When I actually click Go above the Layer 2 control, Image C replaces Image A on Layer 1.  Why does Layer Controller 2 effect Layer 1?  I found this by creating a Display Profile where the layers are not fullscreen and they are offset from one another like photos sloppily stacked on a table.  I didn't see this anywhere else on the forum so I posted it here.
