Dimensioning 4.1.0006

My tickmarks are gone there seems to be no way to invoke them. If I bring up an old drawing with tickmarks they are ok until I tuch the dim.Arch ticks are useless an has so been for a long time. I am a little confused that I seem to be the only one that have problems with dim arrowheads that turn in all different directions. This problem has been around for ages. For now I have to go back to 4.0 to get my tickmarks back.
