there may not be too many people like me who use a mouse pen even for playing games (it is much more comfortable for me than a regular mouse), but it was working just fine until the latest update.
now it does not notice it when I click on something.
I use a Genius Mouse Pen i608x.
Thanks in advance for the help!
I hope there is something that can be done, as i dont have a mouse connected (or like to be.)
Though it is likely that this cannot be fixed on the client side and thus outside of the scope of technical support, it does seem like Blizzard's devs need to look into this.
if you go into wacom settings and change your pen from "pen mode" to "mouse mode", the game will start accepting your clicks.
mouse mode is pretty annoying to use when you're used to pen mode, but if you mess with the speed settings on it, you may be able to find something usable after some practice.
As long as you're using a newer wacom tablet, you should be able to set it up to only do mouse mode in hearthstone, so you won't have to change your settings back and forth. (i have an old tablet which uses the old drivers though, so i can't confirm it.)
It's still not a real fix since it doesn't work as before, but at the very least maybe it can help narrow down the problem for a real fix.
At least some hope :)
