I got this question from TJM through the Enigma forums.
"Hello Jord,
Take a look at these graphs:

http://plikens.no-ip.net/plikens/297xwdcgj/bug1.png
at the second screen you can see that the tooltip shows 'boincsimap' instead of hydrogen@home. Purely cosmetic, but it's still a bug. Is it a known problem ?"
I then checked the pie chart on the right in my BOINC 5.10.30 and found I have two entries for Einstein@Home, both 55.30MB big. They are the same colour as well (pink).
If I then go further down the pie chart and check what projects the mouse-over says it 'sees', I notice that it finds the projects it found first again. I have duplicates of Einstein, Alpha BOINC, Hydrogen, LHC, Leiden Classical etc.
Something weird in the mouse-over code. And difficult to explain.
