Thanks, vegas. I think I can work around it. I generally scan the entire market for my bare minimum criteria once a week and then just use that list all week long to run more situation-specific live scans. Right now my bear minimum list is just over 3000 symbols, so I'll tighten up on my criteria some to make that list smaller.
What the person said that called me was that SD would only "display quotes" for 3000 at a time, but she also seemed ~clueless~ about SD and trading in general. And while she didn't say this, I'm thinking that a scan of the entire market (7000+ symbols) will no longer be available either.
But honestly, 3000 symbols is too dang many for anybody, so I don't mind the restriction... esp if it speeds up performance, which is what I understood to be the reason for the change.
