Hi All

I had the same PIA too and just gave up until this thread drove me to give it another shot to try to fix.

I use dual monitors and stick most of the Window/Menus on #2 and they would never stay put on SU re-boot. 
Stuff you may not have figured out.
Some of the menus are hardwired to stack on top of each others and will refuse to tile down.
[Materials]is the only that seems to allow other menus to tile down below and not move around on SU re-boot and it seems also be hard wired in code.
The sequence below does seem to stay put OK.
[Outliner][Layers][Materials]
-------------------- [Styles]
-------------------- [Shadow Settings]
-------------------- [Components]
I also set other menus on the Active Screen Toolbar (monitor #1)and they do stay put too.
[file loaded][SketchUp Pro][menu][menu] etc.
Just save in a template and at least on the PC it seems bullet proof.
Check it out.
It's Friday here and time for some donuts.
