B2S forced off
What it means
These tables start without their backglass.
Why it happens
controller.vbs never creates the B2S server when ForceDisableB2S is 1 (VPX scripts, controller.vbs; VPX settings, « Disable B2S »).
How Pincab Toolbox detects it
Every VPX settings file present says ForceDisableB2S = 1 (and the registry does not say 0), the table loads controller.vbs and calls one of its LoadVPM or LoadEM, and its .directb2s is next to it.
