Hello,
I have MDI Main Frame window. There is one document with
two MDI child Frame windows. When I open one child frame window
(say, window A) and miximize it. Now if I open the other child frame
window(say,  window B), then window B is automatically maximized.
but window B's Maximize,Minimize and CLose Box disappear, and it
looks like SDI window. As a result I can not restore window B to
normal size.  It  works fine if  window A is not maximized when
window B is opened.  Any ideas ?  Thanks for help.
