Draftsight Multiple Monitor Problems

Hi,

I am experincing an unusal issue with Draftsight 2019 SP2.

If i use DS on my "main" montior it works fine. If i drag DS to the "second" monitor, it does not reconginse any left clicking in the model view.

The screens are identical and are set to extend display

They are driven out of the same graphics card

This issue only happens in DS.

I have tried different Mice and that doesn't alter the issue.

I called Solid Solutions and they dialled into my PC and epxerineced the exact same thing.

If i use windows monitor and switch which screen is the main screen, then the issue moves with the screen - i.e. the issue will only occur on the second screen of the extended desktop independant of which physical screen that is.

This issue never happened in DS2018.

Any ideas??
