Problems tool window

This tool window is activated automatically when the background compilation is confirgured.

The Problems tool window only displays compiler errors that occurred as the result of the automatic build operation. On each autobuild, the list is updated with new errors, and old errors are deleted. If you launch the build operation manually while the autobuild is enabled, the errors from this operation will also be displayed in the Problems tool window as well as in the Messages tool window.
