Erratical Window behaviour and program crashes with two sessions of 3dsMAX

3dsMAX 3d and rendering software has a lot of internal dialog windows, which mostly can be opened in parallel. When I start two sessions of 3dsMAX i often get program crashes or erratic window behaviour (flickering, going on and off) and crashes of one session of 3dsMAX. Today I ended DisplayFusion (v9.8.) and these things were gone. No crashes, no flickering. What could be the cause of this or is there a setting which can solve this?

Hi Holger,

If you add the application to the Compatibility tab in DisplayFusion, and turn on "Disable Application Hooks", does the issue persist after a restart?

Hello Owen, thank you very much for your quick answer. I did what you suggest and after some working with it the second session is stable now indeed. But after some switching off and on DisplayFusion I found out, that DisplayFusion is also responsible for a slow down of other proccesses inside 3dsMAX, wich I suffer since I switched to Win10. The opening of dialog windows is about five times slower than without DisplayFusion. I´m very happy, that I found the cause now but on the other hand I would also be happy if I could use DisplayFusio in the future...

If you disable any of the other features like titlebar buttons and taskbars, does that make any difference at all?

Now I did an update to the new graphics driver for my Nvidia Quadro P5000 and removed DF 9.8. After restart I installed DF 10.0 beta with no further settings. I have a plugin inside 3dsMAX, which is for scattering trees and similar. If you click on an item to edit it opens a control panel. Until I can edit it lasts about 5 seconds until I can edit in this panel. When I switch on DF the same process need about 11sec. When I additional edit the compatibility mode for 3dsMAX and deactivate the application hooks it now is again at 5 secs. So it seemed that the installation of the graphics driver and the installation of the DF beta solved the problem. I will now switch on the titlebar icons and see what happens. Also I will turn on the "Use alternate method to move windows" because without it I got flickering or shaking windows for 1 second after moving a window to the next monitor. I will watch it further... Thank you for your support!
