Focus problem for Win32 platform

["Andrew E. Makeev" <andrew solvo ru>]

Hi,

Is it known Windows issue that focus is missing the parent window when 
dialog is closing?

My program description:

1. Create toplevel window (main_win).
2. Create toplevel window (dialog)
   - dialog->set_transient_for( main_win );
   - main_win->set_sensitive( false );
   we need those calls to emulate modal dialog for current main_win 
only, but whole application (other windows) is still responding on user 
events.
3. on dialog->hide()
   - main_win->set_sensitive( true );
   - main_win->grab_focus(); // I added this string just before I wrote 
the mail, and it won't handle the problem with focus.

Problem:

When closing a dialog on Win32 platforms focus is moving not on parent 
(previous = main_win)  window, but random toplevel window from this 
application or any other, someone told me it looks like "extra" Alt+TAB 
(switch task) is generating on this moment.

Any comments?

Thanks in advance,
-andrew
