Whenever I use the search bar (search box), the results remain rendered on the screen overlaid on top of everything else, including other programs, even if I minimize GanttProject or force “Show the desktop”. The only way I have found to remove the box is if I close GanttProject. I am using version 3.3.3316 running on OpenJDK Platform 17.0.14 in Windows 10 64-bit.
Solved - Double clicking on the search results removes them from the screen.
