When I update or change a line (or lines) to a different layer, the line properties show the change in colour but the lines themselves do not change colour. If I do a print preview or export as a PDF the lines have changed colour, but when I go back into my workspace the lines are still the previous (unchanged) colour. Rebuild and Refresh don't help.. Any ideas?

I'm trying to make the switch from AutoCAD, so expect to be hearing a lot from me...

Cheers.
