      Description

      A very strange bug, filed against 0.4.14-RC-25-geac5f78.
      Please follow the reproduction steps to the point or you won't see it happening.
      When following the reproduction steps, the issue is perfectly reproducible for me.

      Reproduction steps

      • open taskmgr in processes tab and configure it to show the cmdline of all processes
      • close the taskmgr
      • open explorer filebrowser and navigate to C:\ReactOS
      • up to now this was preparation for the test only, now the real test starts:
      • open the taskmgr and watch what cmdline it displays for itself: "taskmgr.exe"
      • close the taskmgr
      • open regedit.exe via double-click from the explorer window
      • open the taskmgr, it will show proper cmdline for both: regedit and itself
      • kill regedit via rightclick from the taskmgr

      Expected result
      cmdline of taskmgr.exe should still be "taskmgr.exe", same as initially

      Observed result
      cmdline of taskmgr.exe is erroneously displayed as "C:\ReactOS\regedit.exe"
      It is no repainting glitch just of the listview, the problem persists even when tabbing through taskmgrs tabs.
      But closing and reopening the taskmgr will correct the wrong cmdline.
