Dear ProfUIS-Team,

while using two monitors in extended desktop mode I got the following buggy behaviour with all sample apps:

1. dragging a wnd to monitor 2
2. pressing its maximize button

Result: wnd increases its size to that of mon2, but switches to pos(0,0) on mon1.

Best regards,

We failed to reproduce this issue in 2.81 and the source code of the <code>CExtNcFrameImpl::NcFrameImpl_SetWindowPlacement()</cod> method already contains the lines marked in your message with the // added comment.

We have fixed the problem using the following workaround:

File: ExtNcFrame.cpp
line: 501 (added)
function: bool CExtNcFrameImpl::NcFrameImpl_SetWindowPlacement( const WINDOWPLACEMENT & _wp )

pWndFrameImpl->SendMessage( WM_GETMINMAXINFO, 0, LPARAM(&_mmi) );

		_mmi.ptMaxPosition.x = _mp.m_rcWorkArea.left; // added
		_mmi.ptMaxPosition.y =; // added

		CRect rcMove(
			_mmi.ptMaxPosition.x + _mmi.ptMaxSize.x,
			_mmi.ptMaxPosition.y + _mmi.ptMaxSize.y
The bug appeared in v2.80 (and might be already fixed in v2.81?).
