Have this strange experience that Keepass Add entry Popup keep re-launching and refuse to close off selecting the “X” or “Close” button.

Other strange encounter is the disappearance of “insert” behaviour using the keyboard. Keyboard also fired up paste function when I press the “shift” key.

All symptom point to keyboard problem. I’m using a bluetooth keyboard. Tried rebooting the computer does not help. Re-inserting battery on keyboard doesn’t help.

Eventually, the move that help is disabling bluetooth on Windows 10 and re-enable.

Hope this will last. Lets observe.
