Page Up Doesnt Work?

Hey I just wanted to post this because this had been a problem for me and no one could help me.

For a long time I couldnt get my page up button to work, which is very frustrating if you ever want to fly in SL.
Well for those of us who have played There in recent months, you know about a program called Giggles. Its a program designed to let you use multiple emotes at once.
Well anyway, if youve got Giggles installed and its running at all it will auto disable your page up button in certain programs like SL. Also, and Im not totally sure about this but I believe it may also disable your hotkeys.
So if you still play There *snickers* and Giggles is installed, make sure you exit it from the tool bar before playing SL.
Me? Im gonna go uninstall There.

A key symptom of this is also a frequent display of random characters, something like:

,,lu

I can't remember exactly, it's been a few months since I've seen this to know what the exact character sequence is.
