Some info from the forum:
"Welcome back to another round of NHAH beta testing! Please welcome about a thousand new testers, and please read at least the next two paragraphs.
Known issues:
Progress is pegged at 50% during WU calculation, this also means that the "Time to completion" value is incorrect
Suspending, then quickly resuming a WU can destabilize the calculation
Screensaver graphics is still heavy on the CPU and is lacking rotate, pan, and zoom functions
Multiple running screensaver graphics windows may kill each other
Error posting guideline:
If you detect an issue, either a WU processing error, or problem with the website, or anything else that looks wrong, please post a description of it in an appropriate thread in the Beta test feedback forum. While our monitoring software shows every error that your BOINC Manager reports, it doesn't give us what happened leading up to the error, so posting a bit of context often helps. The first time you get an error, please post around twenty lines of Messages tab entries, with the error in the middle. This gives lots of context wrt what was going on at the time of the error. If you get what looks like the same error again, you don't need to post it.
To make the Results page a little easier to read, on the "Your account" page, under the "Work done" section, you'll now find a little "+" link next to the "View" link for results. This opens a page with a results table that stretches out to the full width of the window, and highlights "Client error" outcomes in red. It also shows 50 results at a time instead of 20.
Thanks,
