Does the dialog even make an appearance? Or does it behave as if the dialog is there but unseen?
If the former, I'd say I smell a bug somewhere. But if it's the latter, try pressing and holding your Windows key on the keyboard. Then press the left arrow key a couple of times. Under some conditions dialogs will appear but be out of the viewable space. If that has happened, that key combination should coax the window back into the viewable area.
Wow I feel dumb now. You got it right Rick, kudos!
Yay! It worked!
No need to feel dumb either. On more than one occasion I have been guilty of an inability to see that beautiful forest if it weren't for all those silly trees in the way!
Happy Mo... errrr, Tuesday! Rick
