Tool windows can be moved out of screen …
Install ChordLord 3.01.231
Open your ChordLord via menu Tools… ChordLord.
Move the tool to over the start bar to the bottom of the screen.
(You can not move it back).
I can only reinstall the tool by menu Tools… Tool Browser and then Uninstall ChordLord…
I then have to reinstall ChordLord by re-importing the tool .xrnx and the window position is reset.
