In CExtTreeCtrl WM_LBUTTONUP is not catched correctly. If I overwrite OnTreeMouseClick and supress the handling of WM_LBUTTONDOWN in my function like this: if (nMouseButton==VK_LBUTTON && nClick==0) {
return true;
}
then OnTreeMouseClick with nMouseButton==VK_LBUTTON && nClick==1 is called everytime, I release the LBUTTON. Otherwise, OnTreeMouseClick is called only after a double click. In CExtTreeCtrl::OnTreeMouseClick while handling WM_LBUTTONDOWN, SendMessage( WM_CANCELMODE ) is called. I suppose, this is the reason, why WM_LBUTTONUP ist not catched. Please provide a fix.

Please provide us with more details about your task. Windows sends a WM_LBUTTON*** message to each window independently of the algorithms implemented in message handler methods. If your code eats up the WM_LBUTTONDOWN message, then this does not mean you should not receive the WM_LBUTTONUP message.

The Problem seems to be solved in 2.87.
