Don't you think it would be worth taking a look at whats going on in SOS before taking such hacky and non-productive measures? Its at the least worth finding out if there *is* actually a memory leak no? Cheers, Greg On 9/6/07, Wilson, Phil <[EMAIL PROTECTED]> wrote: > The API you need is called ExitProcess......
