Everything seems to work as expected when running standalone, but when running from my host DAW in ARA, drawing/editing does not work. Pen touches work fine for all other parts of the SpectraLayers interface (eg. tool selection), just not drawing.
I have noticed if the host program does not have focus, attempting to then draw directly in the SpectraLayers ARA edit window without first giving the host focus will result in drawing working correctly for the first touch only (to paraphrase, drawing will work, but only for the first pen touch where the host app did not have prior focus).
