I've had SpaceCal for a good bit but of recent it has decided to cause my vive controllers buttons within steamvr to stop working, I found out that when deleting SpaceCal the buttons started working again and I repeated this for a few and always ends up being me needing to delete SpaceCal to fix the issue.
I'm unsure if anyone has ran into an issue like this cause it was fine the day before but when starting up steamvr it just happened.
