Twitter Karma Time-Out Problem -- Got a Work-Around?

Hello Fellow Warriors,

I LOVE Twitter Karma, and it has been fantastically helpful with growing
my list of followers, but now, just when I need it most, it keeps failing me!

Whenever I try to run it -- even without avatars -- it times out.

Of course, it tells me to run it again and it will pick up where it left off.

That worked until I got to about 9000 followers (sometimes I had to do this
repeatedly), but now, it will never get beyond 90.4% or something.

I tried it on a couple of different computers (even went to Kinko's (uhm I mean Fedex)
one evening to try theirs) and the same thing happened.

And also, it does not appear to run on Explorer, so the one really fast computer I have access to won't work because it only has that browser and I don't have permission to add Firefox etc.

What gives?

Has anyone figured out a way around that?
Or is there another service that provides something similar?
Or do I just have to build a second (or third etc.) list?

Cleaning out the people who don't follow me back takes hours and hours if I do it by hand. Especially since they've changed their interface and I have to actually check if I can send them PMs in that little pull-down menu!

Thanks so much.

Elisabeth
