A simple Delphi application that adds five thousand rows to the database, but during the execution of these actions, I can neither minimize nor expand the application. If I switch to another window, I can’t return the program window from the taskbar, I need to minimize all other windows to see how many percent are completed.
Please explain what this phenomenon is. Is it related to multithreading, which is missing in this application?
