Yes mine were jumping around too. I want to set one size and window position for Omnifocus and have every Perspective populate that window (unless I open a second window).

Trouble is - if you turn off layout to fix this you then lose the ability to for Perspectives to have their own saved settings for internal layout, such as showing or hiding the sidebar.

I hope these two settings (external dimensions/position versus internal arrangement) can be split from the one "layout" tick box.
