Programmes with options that don't immediately make sense.
I'm using the PCB layout part of a package (Altium P-Cad) and running the design rule checker: Makes sure you're not violating distances between parts of the design like pads vs pads etc.
I got an error report but it wasn't showing me where the errors are. Seems only if I click the check box "annotate errors" will it actually show me where the errors actually are.
Wasted morning.
