Draftsight not working with multimonitor

Hi Guys,

I have a standard version of DraftSight. Unfortunately, when I start the program with more than one monitor it does not open at all. When I launch the program only with one monitor it works. Can someone help me with this out because it is quite annoying to disconnect and connect monitors every time when I want to open some file?

I use DELL laptop and DELL docking station D3100. I reinstalled all the drivers but the problem is still presented. All other applications work correctly apart of DraftSight.

Thank you in advance.
