Minor Grid Lines Not Showing

Minor grid lines are not showing in the commercial release and the WIP, I set my grids in millimetres, with major grid lines every 10, and minor grid lines every 1 mm. If I have grid snap on I can still snap to each millimetre but they are not visible ? I don’t seem to recall changing any settings, or maybe I did :(:confused:

When I enlarge the image I can see (rather thick) hints of the minor grid lines…

yes, you’re right, looks like they are a grey/blue colour, will check settings
@RichardZ not sure :roll_eyes:

@nathanletwory @RichardZ sorted, yes background was same as minor grid lines, thanks for the input guys :slight_smile: .
Question, is there a way to change the colour of the major and minor grid lines ?
