I have been noticing that for custom task layouts, that it "seems" to be changing either on it's own OR that adjusting the layout in the task explorer is also changing the layout on the project tasks tab OR perhaps other users change the layout for themselves but it also changes it for me. This should be independant of each other, but I am noticing that changing one changes the other. Specifically, I have a custom layout that we use for the project task tab that is standard and another custom layout for the task explorer to see what the team is working on. These layout choices should be mutually exlusive from each other but I find that the task tab layout changes away from the selection that I want. For the record, it's not everytime. I don't seem to be able to replicate consistantly, but I can confirm that the task tab layout changes what seems like randomly.
