Could not get focus on any of the input widgets while working with MDI application?

[ManasQt]

Hi!,
I have a MDI application which has couple of input widgtes on MainWindow and inside Docking widgets.
When ever i tried to bring up a context menu by right clicking on the QMdiSubwindow, all the input widgets in MDI losing their focus.

Note : QMdiSubWindow has an external window (like a xterm) which is not a Qt widget and Context menu is coming from external window.

Is this a bug in Qt ? if not how can i solve this problem?

any help is appreciated thanks in advance.
