Could I just point out that, over several years now, that DXSpider has
been the only software that has managed to keep up and stay up during
CQWW. There are nodes out there with more than 100 users during this
contest. They cope.

If PC16/17s are truly your problem then other cluster software is not
going to help as they all use PC16/17 (compatibility issue, you see); I
would also say that the 'dupefile' is the only thing that is stopping it
all just falling down in a hopeless mess. You could try doing some
careful route filtering which will reduce (and maybe eliminate) loops.
The only alternative you have is (probably)  DXSpider 2 running Aranea
protocol. And since this is in restricted alpha testing only, that may
be a problem.

What have you been seeing and dealing with and how has it been affecting
windows stuff?
