We recently moved up to SW2018 sp4. I'm finding a few annoying things but the most annoying is that when I show or hide a component in an assembly, it disappears for a moment but comes right back on a hide or comes on for a moment and then disappears again on a show. Only way to make it stick is to do a rebuild. Im hoping this is just a system box that needs to be checked or something silly like that or is this a bug? Nothing can be done with the suspect components in either case but I like to use named display states for operations in a tool and I must constantly rebuild after switching or setting up display states as well. thanks in advance for help.
