Solved: Help resizing when opening a new window?

I hope this is in the correct section and the question seems so ignorant, but it's just annoying me. Yesterday while trying to close a program in my task bar, I double clicked. Which resulted in me accidently clicking on "tile windows vertically" Well no problem, I untiled them. But since then when I want to open a "new window" instead of in another tab, it automatically opens the size of the window as half the screen and vertically. How do I fix it to back where it'll automatically open at full size? Ofcourse I can just manually hit maximize everytime or drag the window to a larger size, but how to make it remember to open the new window full size instead? It's just aggravating me. I'm running XP Home and browser IE7. Thanks =)

 

Open the window to the desired shape/size, then close the window via the menu (File > Exit). This should reset the window size to whatever you sized it to.

 

Simple enough. Thanks much =)
