Irbis - where would the warning go and under what circumstances should it appear in such a manner that it is not a simple irritation to those whom the problem does not affect? It is not trivial even to display a warning, and the workaround is trivial, you just need to throw in a 'set layer visible' action.
In "Go To Layout" and "Restart Layout" system actions tooltip + Layer Visibility tooltip
Ashley, believe it or not but not all C2 users are reading forums. Left alone being instantly teleported to this thread when they spot this problem.
If i would be a new user, and i would use those system actions i would be very suprised and i would try and find a bug in my events that is cousing this. I would think it was my mistake, somewhere. Then after minutes or hours of checking my project events i would go here and report it as a bug.
Or just get pissed.
I would never have gues that its a well known issue which the C2 devs are aware of.
