Hi Ron, can you please post your moi.css and CommandBar.htm files? I'll take a look at what's going on.

That looks like the kind of thing that can happen if something isn't right with flexboxes. MoI uses a layout mechanism called flexbox to arrange that command bar UI horizontally. In your UI either some flexbox properties or some structure isn't right. MoI v3 and v4 use slightly different flexbox implementations and so you can get that kind of thing if you try to apply a v4 UI onto v3 for example.
