I'm having a hell of a time trying to download all headers in the newsgroups I frequent. I have three of four that have 40+ million headers. I'll get one group with 77 million headers downloaded and when I try to do the next one with just over 43 million, my system bogs down. CPU activity goes to 100% and header download drops to a few hundred a second after about 8 million headers. Because I'm grabbing 20 to 30 million headers it would be days before I complete. The computer becomes very unresponsive, even to simply cancel the download operation. I thought maybe I've got some kind of install problem. When I try to reset the cache, the cache files are still there (althought the older style cache files have gone). If I delete the new cache files manually, it doesn't seem to help when I try to download them again. When I try to edit group list files, BinaryBoy opens the wrong folder, and I have to go hunt them down. I found my registration key to do a full re-install but was wondering if simply un-installing BinaryBoy will clear the Windows Registery keys.
