I'm using QT4.3 in VS2005. When I use the form designer, and right click and select "Lay Out in a Grid" the widgets in the form are laid out, but I can't see the red lines of the grid that was chosen for me. One time I did see a grid, but I have no idea how I got it to appear. Is there a secret?

Also once it has auto-layout'd some widgets, is it possible to manually adjust them (for example adjust a widget to span 2 cells), or do you need to break the layout and tweak things?
