my H18 started crashing on exit. it works fine while modeling but when I exit H18, it crashes. this happens only when I have view pane on second monitor OR if I tear off view pane leaving it on primary monitor it crashes. I have AMD radeon RX580. this setup worked fine with H17.5 and using second monitor. I have been working with support, they have had me try several things, including installing it on C:\ drive (had it on second drive) - still crashed, made second monitor primary - still crashed, nothing has worked as of yet.
