Regional decimal separator
What it means
Some table scripts or config files may misbehave under your current regional settings.
Why it happens
Many VPX scripts and config parsers assume a dot as the decimal separator — Windows' French regional format uses a comma by default, a documented pain point for francophone cabs.
How Pincab Toolbox detects it
Windows' current number format uses something other than a dot as the decimal separator.
