Welp, this sucks.
The latest Windows 10 update (Fall Creators Update) is officially fucking up with my tablet (Artisul D13) big time. No response on the pen and erratic function on the hotkeys.

At least Artisul is already trying to fix it. Their help forum is down, though.
This sadly means my commissions/YCHs are on hold for some (SMALL, I HOPE!) time.

So yeah, apologize for the inconvenience, especially to the YCH winners.
