on a dual monitor system the render frame window didnt show the rendered Krakatoa particles on the main and focus monitor. If I switch back the RF Window to the second one, the particles appear again.
Olly
Sounds like Autodesk/nVidia problem to me. 
I have used dual monitors since the first version of Krakatoa and have never seen anything like that.
We just send image data to the RFW, we don’t control what it shows and when.
Does it work correctly with Max Scanline rendering?
Yep. Nop with MR, Scanline, VRay and FR. never saw this before. The main screen where it occurs is also the main PhysX. Maybe thats important. Try to switch them tomorrow.
Hm, really seems to be a problem with nvidia and Autodesk. Switched the primary Physx screen and its ok. After switching back to the original config the fault didnt appear again. But NEVER had that befor. And its a completely clean system.
