I would start with zoom. To reset your zoom to default, you can use either: * Ctrl+0 (that's a zero) * on the graphical menu, click the number in the middle of <br><code>- | 100% | +</code> * (menu bar) View > Zoom > Reset You also can try zooming in more by holding down the Ctrl key and pressing the + key a couple times. ---- Does Pogo use Java or Flash?
