Not seeing all parts of popup window

Hi,

This happens occasionally to me with smaller pop-up windows. I have one on the screen right now. It is an HP Update window, asking me if I would like to update now. I can not see the button to click on the bottom. Sometimes I can just barely make out a slightly darker line in the center of bottom line and it will react when I put my pointer there, but not this time.

I did some research and it said I needed MS. Net Framework 3.5 SP1. I had that. It also said I need the MS Net Framework Assistant. I downloaded it but don't find it listed in my programs in Control Panel.

Also, when this happened last week, I did go to HP in Programs and ran the update file. One update was successful and one was not when the HP Installer Plug-In stopped working.

Any ideas?

Thanks,
