There is a very annoying problem on some Windows 10 systems, please see the screenshot: https://s27.postimg.org/r3j7svptv/Acti_Pro_submenu_gap.png

As you can see, there is a gap between root level menu items and sub-menu. If you move mouse to sub-menu not fast enough, you will get submenu closed.

We tried six Windows 10 machines and this problem constantly reproduces on three of them.

Any workaround we can use in frames of version 2015.1 in order to fix it?

Yes we came across this the other day and fixed it for the next 2016.1 maintenance release.  I don't believe that used to be there and our code in this area hasn't changed in a long time, so it could be that Microsoft recently adjusted something in WPF or Windows 10.   The problem is related to the "handedness" setting in Windows and how WPF Popups align differently with the default of "right-handed" on a touch-based system. 

For the next 2016.1 maintenance release, we implemented our positioning logic for this exact scenario do be done in a different way that doesn't trigger the problem.  If you'd like to try a preview build of 2016.1 build 636, please write our support address and mention this thread in your email.

Thank you for the information!

Any clue on what should we try to fix it in 2015.1? Our product is released using this ActiPro version, and we are going to try to fix this in frames of hot fix.

Hello,

Unfortunately the change is within our C# code in how it handles the popup placement for that one particular scenario.  There's nothing that you can change externally or in XAML to resolve it.
