i can't just in version 32 ?
can i in older versions ?

Opera opens a link in another new tab ... always
Yes maybe it is the key assignments... but where can i view/change those configuration ?

Every time i click a link, opera does open it in another tab... i would like in the same tab!

In previous versions i could get that behavior in :
Preferences->Advanced->Tabs->Open Windows Instead of Tabs...

There is no check box in Opera 32 nor even at Opera://flags...

Can you help me please ?
Thanks.
