I am uncertain what you mean by "no links". Are saying that on the other Projects you have run, the cross project links don't report all your Cobblestones of computation and number of floating-point operations but just the numbers for that project?
I know that in Amicable Numbers the cross project link never reported anything but Amicable Numbers work. I reported that in the discussion group but no one was interested in fixing that.
I just looked at the Amicable Numbers cross link for my account and everything is zeroed out.
But as I stated before PG always reported all of my Projects. I am certain because each day I entered the values in a spreadsheet.
Perhaps there is a BOINC problem.
Thanks for taking time to check and post.
