I am running 64-bit Windows 7 Professional with an Nvidia GeForce graphics card (no tablet). Elements 13 ran fine for about a month and then the polygonal lasso tool began failing to select anything (the other lassos worked fine). I just bought Elements 14 hoping the problem was fixed and now find that the polygonal lasso doesn't work at all (no dashed line showing selection). Again, the other tools seem to be working fine. Help!
