Sorry but I've not used Xara in ages and can't remember how (or even if it's possible) to join two lines together. I was using the freehand tool with trace mode enabled to roughlty trace around an object in a jpeg image so I zoomed in on the object in the image I wanted to trace to get better precision. This meant the image was larger than my monitor and I had to trace a bit, press space bar, pan a bit, press space bar to get back to freehand tool, move over end of line to get little '+' sign to continue drawing existing line etc. But on one of the times I must have not got the '+' so was actually drawing a new line and not a continuation of the existing - hence need to get these 2 to join together. Ramble over, time for bed. night night.
