A new version that fixes a bug with P4s and possibly Opterons is available to download. Apparently very high values for "n" > 495xxxx cause version 1.1.0 to crash.
I found one of my P4s was unable to run SOB v1.1.0 but it is OK with v1.1.1 so maybe that was the problem. It just used to crash and wanted to send the usual dumb message to Micro$oft (as if they care?). Naturally M$ never replied with a fix ie visit SOB's d/l site!
