Why such an old version of Opera? I guess you probably have XP or Vista and thus can't install later versions? There was one later version for XP/Vista (2130.80) but it is still over 3 years old at this point ...
because it is this version that restarts (and possibly others) what kind of question?
if it will be useful to developers to roll out let's say the version 2130.90 then here is the bug report please
and also in the absence of other places where you can write, I want to know that by writing about it here it will go to developers
