Before i noticed two of them, both standard not safety, has diferent message priority, they were symbolic preferred < v5.2 while the other two were absolute address preferred < v5.2, now all of them are absolute address preferred < v5.2. By the way for this project i used as template a migrated project from PCS7 v6.1 to v7.0, do you think this could be involved in the error? TomDeWou, only im working on the project.

wolf08 Posts: 14 Rating: (0)	Hey Koy, not really, last thing i tried wassave with reorganization but it didnt work. What I discover at least in my particular case is that this phenomenon happens more frequently when i use copy/paste a lot, so i start creating new blocks instead of copying them even if it took longer,after thati havent had this problem, but again i dont know if i solved somehow or im only avoiding it. I hope this help you a little bit. Just a question, sometimes when i tried to compile or changecfc name or delete it i received a message saying something like the system is busy, i added a pic in a previous post, and normally after receiving this message everything i done dissapeared so both things are somehow related, is the same for you, are you receiving some message from the system? Regards

The only explainations of the behaviour you are experiencingare a corrupt installation of PCS7, a virus or a mall functioning RAID system.
