I installed my second Huion drawing tablet yesterday and love it so far (last older model got misplaced). I've been working on a project since then with no problems yesterday. Today, there were a few minor glitches using Affinity: Document suddenly moved off to the side so half was in view and I couldn't move it back using the hand--closed then reopened document and it was fine. Also, when I applied the "outline" effect to a layer, it would reset to "0" outline when I left the effects window...Now, I cannot paint on a layer! I tried restarting Affinity, restarting my computer. It still happens. Even on another transparent background png. It just paints behind the layer, even though I have selected the layer to work on. I tried disconnecting the tablet and working with just the computer's mouse pad. Still no luck.
