    Hi,
    I want to confirm that Signaltap was updated with new features that are not necessarily helpful, at least when you aren't aware of it.
    I'm presently working with 22.4 Pro in a bigger project.
    1. I also experienced the said the "disappearing" nodes (automatically disabled in hierarchy display), but didn't yet fully understand if it's a bug or feature.
    2. More annoying, I repeatedly found newly added nodes hidden somewhere inside an existing data structure. I learned to consider carefully which line has the focus before adding new nodes. If I forgot to do so, I better go back to a safety copy than start searching the hidden nodes...
    I believe it's intended as feature, definitely it never happened in older Signaltap versions.
    Not specific to new version, a wrong mouse move sometimes makes Signaltap crash, e.g. when editing alias fields.
    Nevertheless I love the powerful tool.

      Thank you for your response. Your response makes much more sense than any of the other responses from Intel employees. I expected that this was a bug (or as you say - a new feature). I to love Signal Tap, but it is very frustrating when it crashes or adds a new feature that cause one hours of time trying to figure out what is happening.

    I tried creating a brand new *.stp file, and I get the same results. Hence, if there is a problem with the *.stp file then it is a problem that comes with a newly created *.stp file.

    I thought that I had replied with the above comment, but I guess it never got sent as a reply. I am still awaiting an answer to this question as it is still happening and I n=have not received an answer that stops the signals from disappearing. Hence, I would like to reopen this case and keep it open until I get an answer. I am not sure how to reopen this case. I tried but was not able to do so.
