I'm drawing a wall section and have some lines drawn with the Hidden line type. Sometimes when I select the line and then drag one of the end anchors to change the length, the scale of the hidden line pattern becomes miscroscopic, i.e. the dashes become VERY VERY small such that it looks almost like a solid line when zoomed out (or the dashes and spaces are like 1 pixel long on the screen). Has this happened to anyone before? The only remedy I've found so far is to just blow the line away and draw it over again.

*edit* oh and it only happens to that one line I edited, all the other hidden lines remain fine.
