Blocking pop-up not working

Blocking pop-up not working at times? It seems when using my application quickly and double clicking on a selection grid to open a pop-up the pop-up that is set to be a blocking pop-up can at times open twice and then the pop-ups are not blocking and the form behind them is editable. Any suggestion besides displaying the form in content?

This is a known issue, and solved in one of the later releases (3.2.0 Afaik)
