Hi,

I'm working with two monitors/screens, and I found out a critical bug.
Steps to reproduce:

1. Run application with RadDocking control which contains 3 panes. Place the app in the screen #1.
2. Drag out one pane and drop it in screen #2.
3. Drag out another pane and drop it into the the first pane we already dragged out (So they will share equal space). In other words, drop it into the new ToolWindow from step 2.
4. Now, from this ToolWindow whice contains 2 panes, drag out the right pane.

Expected: The mouse cursor holds a new ToolWindow which created for the dragged-out pane, and its state is WindowState == Normal.
Actual Result: New ToolWindow is created, but instead of appearing under the mouse cursor, it appears in the first screen, while its height is something very short like 50, and its width is as the width of the first screen. If you leave the mouse button (DragEnd event) and try to drag this short-height ToolWindow in the direction of the second screen, you'll see that it starts to get wider until you reach the the edge of the second screen with the cursor and then it stops to get wider.

Note: My screens showing my desktop in the mode of "Extend".

Please help to work-around this bug...
Big Thanks!!!

I missed a step in my steps to reproduce. You need to maximize the first ToolWindow, and then it reproduced.

So it goes like that:
1. Run application with RadDocking control which contains 3 panes. Place the app in the screen #1.
2. Drag out one pane and drop it in screen #2.

3. Maximize the ToolWindow you just created.

4. Drag out another pane and drop it into the the first pane we already dragged out (So they will share equal space). In other words, drop it into the new ToolWindow from step 2.
5. Now, from this ToolWindow whice contains 2 panes, drag out the right pane.

You can reproduce that here:
https://github.com/telerik/xaml-sdk/tree/master/
In "Docking" folder you got example project which called "RestoreFocusOnStateChanged".
The dlls in the example are old, but I'm working with DLLs of Q1 2015 and it still happens...

One more thing.

I've noticed that when the ToolWindow that placed in the 2nd screen is created by those three line:

RadDocking.SetFloatingLocation(pane, new Point(targetScreen.WorkingArea.Left + 0.1, targetScreen.WorkingArea.Top));
RadDocking.SetFloatingSize(pane, new Size(targetScreen.WorkingArea.Width - 0.1, targetScreen.WorkingArea.Height));
pane.MakeFloatingDockable();

Now the bug isn't happening.
After this code runs and create the first ToolWindow, I dock a pane to this ToolWindow, and then undock it - Now, the undocked pane in its new ToolWindow gets the floating size we set in the above code snippet.
