DS2020 SP2 Right Click Menu fault

Have installed DS2020 on a laptop, have upgraded from DS2019.

I use a second screen attached to the computer, when I have DS on the second screen right click in the DS window all drop down menus appear in the laptop screen not where the mouse is.
Drop down menus firstly drop down in the laptop monitor then on the second use drop down in the second screen.

when my mouse is hovering over a menu item the help box pops up on the laptop monitor not the monitor where the DS window is. Interestingly all items pop up exactly in the correct position on the incorrect screen.

DS2019 was working as expected with no problems with the drop down menus.

I also use S-Works all versions and this program does not have these problems
