Cubase windows not remembering their positions...

I think it might be more Mac related than Cubase, but ever since my computer had a tantrum, and I had to reinstall Mojave 10.14.6, every time I move away from Cubase to another program and come back, the window positions reset themselves, in particular, the marker window I use on every job usually sits on my 2nd screen, and keeps shifting back to the main monitor.

Anyone know of a fix or some preferences I can trash ?

Facing this issue here too. some help is appreciated,
