I've noticed interesting activity with the new Task Scheduler found in SolidWorks 2004. It runs as a process called swBOEngine.exe that shows up under Task Manager. Even if SolidWorks is not running or there are no tasks scheduled it just sits there and creates and then deletes a file named Swbo1.ldb about once every second. This file doesn't show up in explorer but fills my Norton protected Recycle bin very quickly. I have also noticed explorer flashing as if updating at this same rate at times. This flashing stops when I stop the process from running. It also shows using 1-2% of CPU time while running. Dave H
