Well there you have it, each call to addSpreadSheet() creates a new subwindow with

Very good JD200, I totally missed that one.

Solved.

	 mdiArea->setHorizontalScrollBarPolicy(Qt::ScrollBarAsNeeded);
     mdiArea->setVerticalScrollBarPolicy(Qt::ScrollBarAsNeeded);
    setCentralWidget(mdiArea);
    setWindowTitle(tr("Spreadsheet"))
