 MC> why!!
Your description of your problem is so vague that we have no hope whatsoever 
of explaining what is going on to you.  Please supply more details.  What do 
you mean by "later" ?  i.e. When, exactly, did the window close, and what was 
happening at the time ?  What do you mean by "use open os/2 window" ?  i.e. 
What were you actually doing in that particular window ?
