I opened the (edited) sample database but even after the file is loaded, no Grid is open.  I would use the View > Grids menu to open a grid, but the View menu was not shown.  Only File and Tools menu were shown.  It's ok, I can work around that by going to Tools > Manage Grids and open a grid from there.  Once I do so, then the usual menus File Edit View Grid Column Item Tools appear.  Still, it seems like a bug that the file is open but there is no View menu to open a grid from, until I open a grid through Manage Grids.

 

Using 110Pre3, but I saw this problem before updating to 110Pre3, not sure when I first saw it.
