AutoCAD Inventor :: Thin Red Line In Measure Command Not Shown

Inventor 2014.

When you measure something with the distance command, according to the type of file, the last zoom you did, your graphic card and probably the speed of the wind, the little red line won't show.

Normally when you measure something, a thin red line is shown were the distance is calculated. But in my laptop, and both pc's of my client, Inventor shows this line only in parts, not in assemblies. I've got a Quadro 2000M, my client got Quadro FX 1700 and 1800, all with the recommended drivers.

So I tried with 3 other laptops. On one of them (with a K2000M) if you do a measure right after the file open, it give you the line, if you zoom with the measure command open, the line disappear and won't show again until you close and open the file again. But if you zoom without the command active, the line is shown normally. But it's not working like that on all machines.
