I'm using BOINC Manager v5.4.9 and have 4 uFluids tasks that I aborted as the predicted time was nearly 26 hours each (and I hate LRMs). Now I cannot stop them displaying. How do I get rid of them?

I have stopped and started BOINC. This fixed the LHC tasks that wouldn't upload.

I have re-booted the pc (WinXP Pro SP2).

I have clicked update on each project in my list, including uFluids of course.
