If you find that the Control Panel or any other dialog is no longer visible, it could be because it has been positioned outside of the viewing area. Here's a way to fix it.


First, this usually only happens with a particular sensor.

  1. Exit DevWareX.

  2. In the Windows search window, enter "regedit".

  3. Select "Yes" if the warning dialog appears:
    "Do you want to allow this app to make changes to your device"?

  4. On the left-side of the app, expand to the following
    Computer\HKEY_CURRENT_USER\Software\ON Semiconductor\DevWareX

  5. For the sensor your have (e.g. AP0102AT), right-click and then select "Delete".

  6. Start DevWareX - you should now be able to see all windows.

  7. If you still don’t see your dialogs, then right-click “DevWareX” and select "Delete"

What those steps did was delete the various dialog "geometries" - where they were located.

If that doesn’t work, then use the “Bug” icon to report the error and the Demo SW will follow up with you.
