Using finger to make selection.

SL7 Pro Stand Alone no selection issues

SL7 Pro as ARA
selection - lasso, polygonal, elliptical …
Using the mouse or the pen all ok
when using finger above 1000 or 2000 kHz all ok
but if using finger I attempt to select below 1000 or 2000kHz can’t do it.
If using finger I start above 1000 or 2000kHz I can select all the way down.

Very strange!
