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

You may want to log a bug for that.

Thanks Chris. I have been working with Jenny and have tried many suggestions, nothing seems to work. should I still submit a bug for it?

Yup! When you log it, please include as much info about your system as you can. The details listed in Help > About Houdini > Show Details would be great, along with an example scene file. Thanks!

Update on this: SideFX was able to reproduce this and have fixed it with daily build H18.315. So many thanks to Jenny and the SidFX staff for working with me on this. Y'all are incredible.
