I remember that HTTrack used to crash on me too, whenever I attempted to view
the details of a file in the download queue (by clicking on its URL).

Sometimes the program would crash before the window even opened, other times
it would crash soon after the window opened.

But... I've not found this problem for a version or two now, and have been
able to open the actions window.

We did move from WinNT to Win2000.. but I'm not certain if the problem went
away at the same time..
