Every time you start up the wacom tablet switcher you have to make sure that the calibrate or mapping tab is the active one.
Basically the tab similar to this one has to be in front or the tool can't access the proper combo-box.
You''ll also have to re-run the set combobox function because you deleted your .ini file
If your wacomtablet.cpl file doesnt exist in C:\windows\system32 you'll also have to rerun "find wacom control panel"
Leave Fabrice mode off. It only swaps the primary/secondary monitor mappings. Please read the release notes before trying random things...
