Ok, I attached what I hope is a usable sample of the language-learning files that crash Kagu and the uk program. (they work beautifully in canola, I just discovered). If this one works ok, maybe it is the large number of them that causes the problem.

When I ran Kagu scanner on this, I saw that lots of interesting picture files were being downloaded, some of which seemed possibly inappropriate for language learners -- full frontal male and female nudity, for example. But it kept my interest, if It had worked. I turned off the high rez and download options to make things as easy as possible for Kagu.
