*A memory leak occurs when a program obtains memory from the operating system for its use and then doesn't return the memory to the operating system when the program exits.* Almost. a Corrected defintition would read as follows... A memory leak occurs when a program obtains memory from the operating system for its use and then doesn't return the memory to the operating system as it executes. Even programs leaking memory will have their memory returned to the heap when the process terminates. The OS tracks which process' allocate memory so even if a program leaks when it terminates the OS can reclaim the memory as the PID for which the memory was reserved no longer exists. Leaking programs are easier to spot in NT because you can monitor process size over time and watch it grow. Generally programs that run continously like device drivers, tsr's etc cause these problems as the rest will clear up the problems when they terminate. Sean
