           Summary: Keyboard input focus is lost after closing a window
           Product: kde
           Version: unspecified
          Platform: Fedora RPMs
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR
         Component: general
        AssignedTo: unassigned-bugs at kde.org
        ReportedBy: bruno.vasselle at laposte.net


Version:            (using KDE 4.3.1)
OS:                Linux
Installed from:    Fedora RPMs

When I close a window, the input focus is not restored to the window that kwin
decorates as the new active window. 

Scenario:
- open a konsole
- from konsole, start kate
- close kate: kwin decorates konsole as active - as expected - but keystrokes
result in nothing.

However, ALT+F2 ALT+TAB ... still work. Indeed, switching back and forth to
another application restores the input focus. If no other application is open,
opening a new kate with ALT+F2, then switching back to konsole with ALT+TAB
also restores the keyboard input.

The problem is not specifically related to konsole or kate: I observe the same
behavior with whatever KDE application I've tried till now, namely konqueror
and kmail. If I open konqueror, type in something in the URL input, then close
konqueror, the keyboard is lost. However, if I open konqueror and just close it
(without typing in an input field), there is no problem, and the focus is
correctly restored.

This might be related to the X server, but it's definitely specific to KDE (or
maybe QT). I could not find any other application where closing does the same
thing.


My install comes from a fedora 11 x86_64, with updates:
  kdebase-4.3.1-2.fc11.x86_64
  xorg-x11-server-common-1.6.4-0.1.fc11.x86_64

I've used X drivers NV and VESA, both with the same result.

Yours for further investigation.

Bruno
