I've been very frustrated with this, because it keeps disconnecting me, even after unloading all of my remotes. If I'm idle for a few minutes, I get * [10053] Software caused connection abort. I've noticed this, regardless of the network that I'm on. I recently started joining EFnet, and last night I noticed serious lag also. Any ideas about what would cause this and how to fix it? Thanks.

Get ready to do some reading and testing.
