Susan, first, I'm no expert but had a similar problem. I spent 30 minutes
on the phone with Dell support ... (and later realized that using Google I
would have rec'd the very same answer) .
You will have to edit the registry. If you are uncomfortable doing this,
have someone else do it for you.
Here's what I wrote (or copied from Google after I located the same exact
registry location) -
Go to your start bar, click run, type "regedit" and then once it loads find
Back up this key folder if you wish and then delete the upper and lower
filters (note most of the time the upper filter key will be missing).
Right click and delete upper and lower filter [end]
I had this problem under Vista Home Premium.
Check this link (from MS) out as well ....
I hope this does the trick. Dave Horne
