I am trying to draw a simple line, from left to right, with an arrow on the end, like this:  ----------------->

I make the line, go to Fill and Stroke properties, seld an end marker and I get something like this --------------------^
(the arrow head is pointing upwards to the end of the line).

what is going on... you would think it would point away from the end of the line, but it is point at the end of line, perpendicular to it.
