for some reason they don't keep their size. position is saved but preview window gets streched while console gets squeezed ....

I have a similar thing in the Material Editor, but only when I re-open it after having had the enlarged image preview in the texture picker dialogue open. The texture picker box then opens resized to the smallest possible size, while the image preview box is unchanged, but detached. Maybe it is a gpu driver issue? I haven't updated mine for a while...?

Never had a problem in Studio, or the Sketchup plugin though.
