Doesn't this new version use tabs?  This sounds like the perfect time for them.  You want a different window open exactly in the same place, open it in a new tab.

Otherwise, I think you used to be able to hold the shift button down when you clicked the 'x' to close the window and Windows would remember sizing and position.  If you do that once, I would think that any subsequent windows would open same size, same position.

None of this worked, guys    at least with IE7 b.3
In another post around here https://forums.wincustomize.com/?ForumID=68&AID=94572#739202
there is this same discussion. In the post yraq says

When you open the second window, drag it to full size. Close the 1st window and then close the resized window. Windows will remember the re-sized window whenever you open the second or multiple's there of.

but that didnt'work for me either. I remember doing the same stuff before and it did. Is it a problem with IE7? I don't think it is for I'm using the same stuff in my notebook and it works fine. Just don't ask me how I did that   That's why I want to customize the process.

Still quoting the post there's a http://www.theeldergeek.com/maximize_internet_explorer.htm but it was fruitless again.

I know how to use tabs, all right, but sometimes you click directly on a link, like when you want to see the details for a skin here in WC, for instance, and you just don't remember or don't wanna use tabs for that one. That's when my question arises. Thank you all for the tips.

After insisting stubbornly, I actually DID make it work. At least before re-booting my PC.

I followed yraq suggestion: Resized the second open window browser to the position I wanted (not closing the first one), closed the first one (usually maximized), surfed on the second one not resizing it, just to make sure   , and then closed it. IE did remember it the next time I clicked on a link leading to a second browser window. It just didn't open centered, but it's another story.

Any tips?

Thanx everybody!

get that ugly blue Luna skinned as soon as possible

???

So you want to make links open in a maximized window? well the whole reason they added tabs, was that there is no need for new windows.

So that pop-ups controlled by you (ie, you clicked a link that would normally open a new window) open in new tabs, go to Internet Options on the Tools menu and select Settings in the tab area, where it says When a pop-up is encountered: select always open in new tabs, that should do the trick.
