I have a flyout that can open, for example, a Browse button which brings up an open dialog.  However, when i click this button, the flyout itself disappears.  How can i change this behavior to keep the flyout open during this operation?  I have included a sample application below.  i don't want the flyouts to fade away when i click a button in them.  i assume this is because the flyout loses focus, but how can i have it remain open while using the dialog that has popped up?
