Hi Slava,

The flash is caused by a combination of two things:

1) The MainFrameBarManager registering the ChildFrameBarManager. If you do this ahead of time with RegisterMdiChildTypes, you can avoid this.

2) The bar resizing. If the new BarItems are larger than the old ones (or the old ones don''t exist), then the bar is forced to resize after the merge, causing some flickering. There are two ways to avoid this. You can either add an appropriately-sized BarItem (such as a Help or About option) to your pre-merge bar or add an appropriately-sized blank StaticBarItem with a high merge order (such as a single space or a completely transparent image) to your pre-merge bar.
