Bill,
Here's some other ways to get around this. Let me know if you can't get anything to work for you.
Q> On my screen, when I drop down the 'Pen' menu, the list stretches beyond the bottom of my screen. If I move my mouse to use my scroll bar, then the list disappears.
WR> There are a few solutions that have been discussed.
1) You can use "Ctrl" and Plus or Minus keys. The Browser page will be enlarged or reduced in size.
2) For the same results you can also hold "Ctrl" and use your mouse wheel.
3) If you have a PC and have a center mouse scroll wheel, you can just use that while hovering over a drop down menu. The screen will scroll and display the rest of the pulldown menu.
4) Use the Index feature of the menu for a temporary workaround.
