I recently upgraded my AMD R9 290 which worked fine with Eyefinity and DisplayFusion to a nVidia GTX 1070Ti and nVSurround has many issues. One of the issues I see with DisplayFusion is that the Windows 10 Tasbar in the middle monitor doesn't stay in a fixed position related to windows open in the middle monitor.

Opening windows like File Explorer, browsers, or apps appear fully on top of the taskbar for just minutes then randomly go beneath the taskbar and to fix this, I have to unlock the taskbar, enlarge it a bit by dragging it upward, then back downward and lock it again, then windows will fully appear on top of it again.

Attached are pictures of the issue. First one is the correct position and second one is the incorrect position.

Help would be much appreciated.

Yes, nvsmartmaxapp and nvsmartmaxapp64.

Thank you very much for the reply.

I did that and after the reboot, taskbar is spanned across the 3 monitors, not in the middle monitor but start menu and calendar opens in the middle monitor fine.
Also clicking on "desktop" option in nVidia control panel crashes it now.

I enabled MultiMonitor Taskbars and then disabled the 2 side taskbars. Now it is only one taskbar in the middle monitor the way I like it and hopefully the issue does not appear again.

Thank you very much for the help Keith.
