I just did a full re-install of my OS and noticed a new version of CPU miner was out (Before I was on 2.3, first one with stratum built in). Anyway, I've installed the new version and while it works, with the same hash rates as before, I'm noticing I'm getting a ton of "accepted xx/xx (%) (booooo) compared to the older version. Has something changed in newer versions? If I stick my old boot hard drive into the machine the 2.3 version of CPU miner on it, it works on the same pools with nearly 100% accepted rate. With this new version I'm getting accepted rates around 60-70%.
Weird. It would be nice if you could try all versions from 2.3 to 2.3.3 (they are all available at SourceForge) and see which of them seem not to work. Also, please post (or send me via pm) the exact command-line options you are using so that I can test if there's a problem with the server you are connecting to.
