SignalTap II problem adding nodes

Do you have a SignalTap .stp file added to your project? (I'm just taking a guess, but naturally without one, I could see this not showing up). Most people I've seen using SignalTap don't do it this way, since it can be a pain to dive into the Technolofy Map Viewer, sorting through huge lists. I find directly from the .stp file you can add a signal to tap and open the Node Finder, which has a SignalTap (Post Compilation) filter to only look at post-fit nodes. You can wildcard the name you're looking for and hopefully find it much faster.
