Grid text selection issue with FF and IE

Hi,
I am using Grid component with Vaadin 7.5.5 to display my data.
One problem we have experienced is in FireFox or IE, the user cannot make a copy of a text by selecting it with their mouse.
As soon as the user releases the mouse button, the selection gets unselected.
It works fine in Chrome though.

I have looked around the Vaadin forum, but can’t find any answers or any related topic to this.

Did anyone experience it?
Is there any solution to it?
