Stephen, I have seen this and I believe what is going on is that any Relative Prop added via constraints manager can only be viewed by Constraints Manager. It also may have some to do with XNET level properties that cannot be viewed or changes outside of Constraints Manager because the find filter covers NETS only. I really have not dug into it too deeply but I have found myself doing things more and more via Constraints Manager. Hope this helps, Michael Catrambone UTStarcom, Inc.

Delays, now in Version 15 they are not there? Is this a bug? The main problem is viewing the Relative Prop delays in the Allegro Viewer, I can't seem to find another way other than using the filter.
