Yes it is possible. This is exactly what ROViewStack is about. A ROViewStack is a stack of views. It is usually used to contains menus and popup, triggered by the added view. This is convenient to not have the buttons or popup be under the effect of zooming in and out. Inserting elements in the stack makes the elements not subject to the variation of the camera for the added views. Here is an example: -=-=-=-=-=-=-=-=-=-=-=-= | stack view el1 el2 | view := ROView new. el1 := (ROEllipse red size: 30) element. view add: el1. el1 @ RODraggable. el1 translateTo: 100 @ 100. stack := ROViewStack new. stack zoomInButton; zoomOutButton. el2 := (ROEllipse green size: 30) element. el2 @ RODraggable. stack add: el2. stack addView: view. stack open -=-=-=-=-=-=-=-=-=-=-=-= Alexandre -- _,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;: Alexandre Bergel http://www.bergel.eu ^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;.

This is a recurrent situation. For example, if you zoom in, you usually not want to have the size of the button or popup text to increase.
