Yes, 800x600 resolution can solve the activation window problem. After you finish inputting all information and before you file tax, you may experience similar difficulty if you choose to pay either state tax e-filing fee, or audit assistance fee, etc. Unfortunately 800x600 resolution alone cannot solve problem over there, you may also need to change size of the text to 100% to finish that window. But if you choose to e-file federal tax only and mail-in state tax, you will not experience that difficulty any more.
