Abstract
A debugger that is multi-task aware and capable of providing symbolic support to a graphical user interface (GUI) is disclosed. The debugger disclosed communicates with a multi-tasking kernel nested within a driver of the operating system within the 0 privilege level. The multi-tasking kernel distinguishes among the rest of its environment where a graphical user interface executes the driver tasks being debugged. The multi-tasking kernel, in cooperation with the debugger runs each element on a different thread of the same machine, thereby allowing the debugger and the driver tasks being debugged to continue to run without stopping operation of either the graphical user interface or the operating system associated with the graphical user interface.
