Import options dialog box not showing while importing CAD files

Hi, I notice that in the last few versions of 3D Stager the Import options dialog box doesn't show itself while importing CAD files. I usually import IGES files and all worked fine in the past, while importing you could determin the accuracy level of the import like Very High (for the tesselation) etc. In the last few versions although you can choose "show model import options" in settings, it doesn't really work and the model is imported directly with medium/low tesselation level. Does anyone know anything regarding this issue? Alon.
