Last few weeks a have had really annoying problems when some program stops responding and I had to terminate it using task manager through End task. Every second time when I terminate some program I do succeed to terminate it (after one or 2 times) but then dwwin.exe (and often dumprep.exe) process is still running and from that time on I literally cannot start any new program - I can just use what's opened. For instance, when I try to start MS Word (or any other, Mozilla or whatsoever), I see the appropriate process has been started (it uses memory and is visible on task manager), but there is no visual sign of it (no window and is not on the taskbar) so I cannot actually use it. And that's not all - I cannot Shut down or Restart or Log off through Windows either, so the only thing to do is to Reboot by pressing the button! Sometimes windows works just fine, but the program I terminated cannot be started until I reboot. Everything happens "on random". For instance, some programs gets an error so I terminate it, start it again, terminate it, but third or fourth time I cannot due to above mentioned windows problem. I'm using Windows XP SP2. Is this a Windows XP problem?
