Windows 7: Annoying IE feature?

I use IE9 for a lot of browsing and sometimes I inadvertently click the 'Open in a new window' rather than 'open in a new tab' which then produces an offset for the new browser window. Since my browser window is not full screen (I use gadgets on the right-hand side) this often results in the new window overlapping the gadgets and what is worse is that when I close the browser it retains the shifted location on reopening - even having closed all windows or tabs. I haven't bothered searching for a solution for this as I try to be careful but it is really annoying. Am I missing a really simple tweak to stop this behaviour?

You can grab the tab and bring it over to connect with the previous IE window. You sort of drop the tab off in the first window (IE9).

Enhanced tabs - Microsoft Windows

Give this a try.

1. Control Panel > Internet Options > General tab
2. Click Settings button in the Tabs section
3. Select "Enable Tabbed Browsing"
4. When a pop-up is encountered: select "always open pop-ups in a new tab"
5. Open links from other programs: select "a new tab in the current window"
6. OK your way out of the dialog boxes and restart your computer. See if this helps.

Thanks chaps, I didn't have this one selected - "always open pop-ups in a new tab" but that hasn't solved it and the only thing that works is to grab the window and position it where I want before closing it.
