Do you mean, when you open a new browser it's not full size? That happens when you'vd adjust the size of the browser down in some way. Like when you want to see what's on two websites at once. So you make the browsers half size (or whatever) so you can see what's on both pages at the same time. THEN you closed one of them while it was in that small size by hitting the red X in the upper right corner.
The remedy is to open a browser, click the button left of the red X so that it's
full size, then closer it by clicking the red X. Once that's done, click to open a new browser and it should be full size again.
I guess what happens is Windows remembers how you had your browser the last time you used it. Then, when you open up IE again it opens the browser in the same way you used it last. I guess this is to save you from having to adjust it down again. Shrug.
Lemme know if this works.
