Tom,
Yesterday I switched to US Standard User Preference Scheme 9. A thread on this forum said that this is the User Preference Scheme that I need to get the Multiply Option to show up on the Mouse Right Click. Even after I chose the US Standard User Preference Scheme 9 the Quick Layers was showing up. Trying to find the Quick Layers I tried each of the other two Schemes that are available. Quick Layers was not available under either of these schemes. I just tried shutting down my computer and restarting ArchiCAD. Now quick Layers are back. I think that the disappearing Quick Layers might be a bug.
Thanks,
John
