i*i is shorter and (maybe) a little faster with many numbers

a and b already are of the type byte, so casting them will not do anything. However, the addition operator + returns an int (as bytes are not necessarily used as numbers, so a + b implicitly does is (int) a + (int) b), hence we do need to cast the result.

Nice one - glad I could help!

Thank you for your service.

This error happens when the code is outputting too much data to the log window. So this could be caused by using Console.WriteLine a lot or by writing to the log window inside an (infinite) loop. Have a careful look to make sure the loop is being terminated.

If you aren't sure, feel free to post the code and check the "Mark as having spoiler content" checkbox.

not an issue.
