Event leftButtonDown/isLeftButtonDown problem in Firefox

[mihai007]

Hello.
I am using Firefox 6 and smartgwt 2.5 and it seems that when I scroll using the mouse wheel over the list records the event.isLeftButtonDown() returns true instead of false. Tested under chrome, safari, opera, IE9 and seems to happen only under Firefox.

listgrid.addRowOverHandler(new RowOverHandler() {
  public void onRowOver(RowOverEvent event) {
    event.isLeftButtonDown(); // returns true when mouse scrolling
  }
});

Any idea why is this happening and what workaround I could use?
