When right clicking, menu appears on second screen

I got a dual screen setup, and I use synfig on my main screen. When I right click, the menu appears on my second screen for some reason.

I also am using a tablet that is set up to only cover the main screen, and when the tablet is plugged in synfig will ignore mouse clicks, so I can’t just use the mouse to click on the menu

So I either have to turn off the second monitor or my tablet, which is very inconvenient. Any way I can avoid doing that, even if the poblem isn’t completely fixed?

What is your OS?
What is your Synfig Studio version?
Did you download an official build or did you compile yourself?

On windows 10, synfig v. 1.4.4, official build

Could you try the development version 1.5.1?
