The Task Manager window lists all the currently running GPS operations that run in the background, such as builds, searches or VCS commands.
The Task Manager is opened by double clicking on the progress bar or
using the Tools->Views->Tasks menu, and can be put anywhere in
your desktop.
For each of these tasks, the Task Manager shows the status of the task, and the current progress. The execution of theses tasks can be suspended using a contextual menu, brought up by right-clicking on a line.
When exiting GPS, if there are tasks running in the Task Manager, a window will display those tasks. You can also bring up a contextual menu on the items in this window. You can force the exit at any time by pressing the confirmation button, which will kill all remaining tasks, or continue working in GPS by pressing the Cancel button.
