Running the time-consuming task in a separate thread will prevent it from blocking the main thread, allowing the GUI to remain responsive to the user. This is a common solution for implementing responsive GUIs. Breaking and checking for events while running the task is also a possible solution, but it can be more complex to implement and may not be necessary depending on the specific task being performed. Asking the user if they are sure they want to run the task and disabling the GUI during the task are not effective solutions for maintaining GUI responsiveness.
