GoOverview with DockStyle.Top

Using Win Go version 2.6 and an application based on Demo1, I would like to dock the Overview window (along with a TreeView window and a Palette window). I can get this to work if I use DockStyle.Fill for the GoOverview window (and Top/Bottom for the other two).
However, I would like for the TreeView to have the fill behavior and have a fixed size and DockStyle.Top for the OverView window.
When I do this, the overview window is blank.
Is it possible for the GoOverview window to have DockStyle.Top ? If so, any ideas what I might be doing wrong?
Thanks, Doug

Maybe it started off with zero size (Width, Height). Try assigning some reasonable initial values for the GoOverview.Size, before adding to a Panel.

Thanks, that was my mistake.
