Every time I relog, or reload, the position of the Cost Details resets, often getting in the way of tabs or other windows.

Moving it, because it's in the way

After reloading

For me it did indeed keep its position after reloading
are you maybe using addons that interfere with the moveability of windows?

Not anything specifically.
I do use RealUI which allows me to move any window freely. And I'm not sure if this started after I updated that or not.
Edit: Even with RealUI disabled, still happens

I do also get a LUA error on opening a prof frame, relating to CustomerHistory frames, so maybe related?
