Have I gone mad? Since I installed 7.6.6 it's running two projects at the same time but I'm sure before it only ran one at a time. I can't find anywhere to tell it to only run one project at once?

The projects your BOINC is attached to.
The projects that your BOINC is actively running.
Post the first 40 - 100 lines from your BOINC Event Log (CTRL+SHIFT+E), including it showing what your BOINC is doing, which project tasks it is running.

You have a quad core CPU and are allowing two cores to be used, using the local preferences in BOINC Manager. There you've set Use at most N % of the CPUs to 50%, if you want BOINC to use only one core, set this value to 25%.

By the way, for terminology.
Project = Einstein, Climateprediction.net, Seti@Home, Primegrid, etc.
Task = the work you run from a project. One task per CPU core.

Me help desk amateur way too late again...

Thanks! I must have fiddled too much!

I'm sure the settings used to explain that better. I did know that but had forgotten and started tinkering :(

Thanks for the help!
