Wrong window maximize on two monitor systems.

[chuuddo]

What steps will reproduce this issue?

I have two monitors and after update from v1.4.1 to v1.4.2 window maximizing start ignore taskbar with z-order behind tasbar (see screenshots). On one monitor systems this issue not reproduced.

v.1.4.1 two monitors maximized window.

v.1.4.2 two monitors maximized window.

Expected outcome

Window maximizing should work same on any number of monitors

Environment

• MahApps.Metro v1.4.2

• Visual Studio 2015
• .NET Framework 4.5.1

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

[chuuddo]

@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...

[chuuddo]

@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.

[punker76]

@chuuddo Can you try this one? I think I optimized to much in last release 😁
MahApps.Metro.zip

[chuuddo]

@punker76 it works fine, like in 1.4.1!

[punker76]

@chuuddo Thx for clarifying the problem and testing!

When will you release 1.4.3 ? This happens on systems with 1 Monitor too.

I dont want to go back to 1.4.1 😄
