mat first of all this is a great benchmark. I really like it Nice work!
I noticed something during the last two days. After the calculation is over you get the "Calculation done" pop-up window. Same as running normal SuperPi32m I kept the extra window open and clicked on "Submit to HWBot", saved the result and ran again. After the bench was over the "Calculation done" window came up and I wanted to save but after clicking on "Submit to HWBot" nothing happened. I had to close the "Calculation done" window first before I could save the result.
