(e.g., the entire code segment became one line). Is attachment the only way to do this right? - To track this, I essentially was doing "printf" debugging. It is rather slow/painful. Is there a way to get suspend the tasks, which will then allow people to attach a debugger in time to trace thru the execution. If not, how do people generally debug problems like this? I generally find the ability to debugger-attach to programs and just roam around the stack helps greatly in understanding complex programs quickly (even if I am not looking for bugs). bwolen
