Sorry, this is all my fault and on my side. Actually I had added a Window Rule to my Actual Windows Manager to control the Octane IPR Preview Window. So this has nothing to do with Octane Lightwave.

Also, have been away from the computer for quite a while.

Thank you so much for all your hard work ...

Clicking The IPR button locks up Lightwave and have to use the 'Task Manager" to close it.

It all started when I hooked up a 4th monitor early October. Yes, I should have contacted you but have been down since then. Have you heard anything else from users with 4 monitor setup?

Same result with11.6 ...

I am locked now too (4 monitors). If we lock up when starting IPR, then how did you change where the window opens?
