The way the code is written it sets a couple of vars and then reads back its own values .. no chance of finding the REAL location

In the recent update the following points are addressed:

- Screen insets are used to account of taskbar position and the placement of the instruction frame at top-left corner
- Position option description update

Changes regarding pushing the latest position to window manager are being evaluated.
