Sorry for the late reply, I was on vacation.

Mmh, works for me now.  But this list is ok too, don't worry.

Weird.  I'm having no problem accessing the scipy.org cvs.  Please let me know 
if this problem persists.

On to your bug:  indeed, the dreload() code is far from perfect. 
Unfortunately, it's also extremely tricky, it has zero comments, and I didn't 
originally write it (it was one of the pieces from Nathan Gray I picked up 
when I started ipython).  I'll put your report on the todo list, but this one 
may take a bit to get fixed.  Every time I've had to deal with that code I've 
ended up with a headache :)  But I promise to look into it.

Glad you like it, and thanks for the feedback!
