--- Comment #3 from Mark Dunn <mark.dunn.and.sharon.k...@gmail.com> --- Do you use Options-Calc-Calculate-"multi-threaded calculation"? Yes Yes, I do a lot of COVID-19 modelling, I tried this in the hope autosaves and calcs would be quicker. A clean profile has fixed the deadlock so far, but not the performance. No multithreading. -- You are receiving this mail because: You are the assignee for the bug.
