Recent case: 1. Task Manager Applet crashes and disappears 2. Restart KDE 3 The Task Manager Applet is not restored and is missing. 4. I try to add it back and spend time trying to figure out what it's called. Searching for "Window" (like window list) doesn't show it. 5. I can add the applet but it's added all the way on the right, and I can't move it back to the center, where it belongs. 6. I have to move all the applets I want to be on the right of the Task manager, one by one, to the right of the panel. Reproducible: Always Steps to Reproduce: "Happens every time" above means "happens every time an applet crashes." Clearly if an applet crashes, it doesn't mean that I don't want it to ever come back. Actual Results: Applet never comes back Expected Results: Applet should come back I've seen this problem for about 15 years.
Plasma 4 has been unsupported for several years. Haven't seen this happen in Plasma 5.
