Processes always start in kernel mode, because they're started by the kernel. They typically spend most of their time in kernel mode (for example, whenever they're idle or waiting for I/O). An active process may switch back and forward between kernel mode and user mode thousands of times a second. > I think in user mode, and so there is no reason why it should affect > other processes, even if my application had some memory management > problems. A process which spends all its time in user mode is looping :-) Maybe you should describe your problem. Greg -- When replying to this message, please copy the original recipients.
