Problem: Arctoolbox dialog boxes do not show up on screen


The Arctoolbox dialog boxes do not display on the screen, however, they do appear to show up on the taskbar.


The window position in the Registry has incorrect or negative values.

Solution or Workaround

Change the window position of the dialog box in the Registry.

  1. Navigate to Start > Run, type regedit and click OK.
  2. Navigate to HKEY_CURRENT_USER\Software\ESRI\ArcToolbox\Settings.
  3. Double-click the DlgWindowPos and change the data value to 1,1,1,1.
  4. Click OK.
  5. Close the Registry Editor.
  6. Start ArcMap. Try to use some of the Arctoolbox tools; the dialog box should now be on the screen.
