I found another strange behavior: it seems the first time you start the application pen location always works perfectly, but after the second run pen location breaks.
This happens since 4.0-rc2, the second run on 4.0-rc1 does not break pen location
Thanks for the report.
The only update during this period to wintab32 was winex11: Use active owner when sending messages.
