@chuuddo your screenshots seems to be the same? Damn, maybe I fixed to much...

@punker76 look at ActualHeight on screenshots. If maximized right it should be 1080-TaskbarHeight on FullHD resolution.

Code of window on screenshots.

@chuuddo OK, but in both screenshots the maximization is wrong...

@punker76 dont understand why maximization is wrong on both sreenshots.
I think in 1.4.1 maximization work right. All screenshots made on two monitor system.
