For those of you trying out the new beta version of Opera,the all new opera 10 BETA 2 does not detect previous versions of opera and does not offer upgrading from previous versions.If you want all your passwords copied just do this from a command prompt:

copy "%userprofile%\AppData\Roaming\Opera\Opera\profile\wand.dat" “%userprofile%\AppData\Roaming\Opera\Opera 10 Beta\wand.dat”
