A pop up menu in an application is opening off the screen
I'm using an application called RocketCake (responsive web designer tool) and Mac OS High Sierra 10.13.3.
When I click on the menu to pick a new color the color menu jumps out of the app and onto the desktop but out of view! I have to drag the application partially off the screen for that menu to appear on the opposite side. If I can't get to it, it jumps again. It basically freezes the application because that menu is open.
Any thoughts?
Also, I'm using two screens.
MacBook Pro, macOS High Sierra (10.13.3), 2.8 GHz Intel Core i7; 16 GB ram;
