Answer
Not a bug
The 1003 error means that the tweaker failed to run the injected code as part of the explorer’s process.
This can be caused by an antivirus, which denies access to explorer due to security concerns.
Try whitelisting the tweaker.
It depends on your antivirus or security software. Contact their support service if you need more help with this.
thank you. My IT at Melbourne University have whitelisted tweaker. Great to have it back. Why do office make such stupid non functional features as the windows... If you have more than 5-6 emails open its a bog's breakfast.
