Light problem with movable object

Hello, i have a few question. In my room i have 2 windows. The first is: this place must be full or empty? p.s. ive tryed both.

Next. In this case ive tryed make all window like movable object, cuz i have animation of this part, but like u see on a sill no sun rays, only shadow of frame and of glass(?). And window looks darker then if make it static(if using ao window almost full dark).

And there are a bug with light. If move window in\outside it looklike waves.

Ok here ive tryed make window like static and animation part like movable. Like you see on upside no light bugs, except dark corners and folds.

But there are a bug with frame shadow, it wavelike and i guess it It has been shifted outside.

And here a main bug. This place always white, i cant understand why. And this movable part agains darker then must be. Also ive fixed problem with wavelike shadows sometime but still there are bug with this place but now there are white lines between animated window and other pieace

Can someone help me?

p.s.s. increasing lightmap not always fix problem with those wavelike shadows
