X/Y 5'- for coordinate input not working

[Anonymous]

OK - baffled here...
If I want to draw a wall starting at one corner - hover mouse over corner, input x5'+, cursor jumps to and creates a blue line in the correct spot as my offset point to draw a wall. This works in x/y axes. If I try the same with negative values i.e. x5'-, the cursor jumps to an arbitrary point in the y axes. Anybody have any input on this?

For Imperial Units using "Feet and Fractional Inches" when you are going to the left or down (negative axis) you need to write either 2 (-) or (-+)
• X5'--
• X5'-+

Reason is that after one dash AC is waiting for inches. This is not the case for Feet with Decimal inches and or Metric.
