Window Maximize Problem

[Carmela]

Hello - I think my kids got to my computer and messed up
some settings.
Any time I launch a new window from a website (like going
to another website) or launch a url from my email the
window opens up very small - the bar is about 1 inch and I
have to hit the maximize button to enlarge it. I'm sure
it's a simple setting that has to change, but I can't
figure it out.
Anyone know how to make it so the window opens full screen.

thanks

Click on a link to open a second browser window. Drag the corners of the new
window to full screen. Close the first browser first, second browser second.
Or
Modify the registry key HKCU\Software\Microsoft\Internet
Explorer\Main\FullScreen REG_SZ to "yes".
