I'm running BOINC 5.10.45 on a iMac with 10.5.2.

From time to time I find an icon (sometime two) in my dock that seems to be related to a BOINC project that I'm running. For example, I've got one in there now with the name hadcm3trans_5.39_i686-apple-darwin

When I try to shutdown the computer these cause the shutdown to cancel. I try "force quit" on the icon but it doesn't seem to work.

Any advice?

hadcm3 = [Hadley Centre] [coupled ocean model, version3]
In other words, you're running a climateprediction model.

Shutting down the computer without first Exiting from BOINC is a very good way to crash the model.
And if BOINC (and the model) get shut down first, you wouldn't have this program sitting there to cause problems.

PS
Getting in a plug for the cpdn project, a new version of the slab models has been released to fix the problem of Macs crashing these immediately.
