Hi Polo,
Your explanation makes sense but shouldn't we at least get the selection box/anchors when we click anywhere on a "Containers" type gadget?
I'm finding I can only select a Container, Frame and Scroll Area gadget from the Objects panel (which is also intermittent) or by clicking on the border of those objects.
Panel and splitter gadgets appear to be OK, I can click anywhere on the gadget and get the selection box/anchors.
Make sense?
