Wide white line on the top of workspace Mathcad Prime 5.0
I downloaded a free 30-day full-featured trial version of Mathcad Express from the site. After installation and some working time in it, I noticed that the top edge of the working window gradually turns into a wide white line (this happens when mathcad is constantly turned on from the taskbar in the process).
After some time, it becomes simply impossible to work, because This white line narrows the workplace very much.
What could be the reason and how to fix it?
