I only recieve "The specified request cannot be executed from current Application Pool" Tried Opera, Mozilla, MSIE Anyway, the best realtime system i think would be to integrate time critical routines in a way that they catch interrupts and take care of time critical things, without relying on some more or less known kernel. Like integrating realtime routines in the kernel. Of, course then we need a well documented and configurable kernel, a plus if it is well known, supported, and future safe. Like Linux. There already are versions like this, that allows you to run your code as highest priority, yet you have a full modern OS to back your app, with advanced filesystems, network, graphics, whatever. http://www.google.com/search?q=realtime+linux /Morgan -- Morgan Olsson, Kivik, Sweden -- http://www.piclist.com hint: The PICList is archived three different ways.
