Scroll Lock Hell

I had an interesting thing happen this morning. I went to work on an Excel spreadsheet, and every time I hit the arrow keys the page would scroll around as if I was dragging the scrollbars. After a while I noticed the little "SCRL" in the lower-right-hand corner of my spreadsheet that indicates the scroll lock is turned on. This was most unusual, seeing as to how my keyboard (a Logitech MX 5000) has no scroll lock that I'm aware of. However, somehow the scroll lock managed to get turned on. Since I have no scroll lock button, I couldn't turn it off. I never did figure out how it got turned on, but I did figure out how to turn it off using Window's built-in On Screen Keyboard. Here's what I did:

1. Went to Run under the Start Menu.
2. Typed "osk" (without the quotes.)
3. A little window with a keyboard appears. Click the "slk" button to turn the scroll lock on and off. When it has a red border (as shown in the image) it's on. Otherwise it's off.

I hope this helps someone else out there having the same issue. If so, leave us a comment and let us know!
