Help - Change from MDI to SDI

[conan]

I've installed Opera on a new PC and am desperately trying to get back to using pages within one window. I've loked round and think I need to change from MDI mode to SDI mode, what I can't find is where to do this. Can anybody point me in the right direction?

Welcome to Webmaster World!

Try

File > Preferences (Alt - P)

.. Go to "Windows" and the "Open windows inside Opera workspace" checkbox
