Ak urobíš len upgrade, tak sa ti samozrejme heslá zachovajú (rovnako ako všetky ostatné nastavenia, vrátane rozmiestnenia panelov a toolbarov a odkazov/tlačidiel na nich).
A podľa všetkého sú napr. v XP uložené v súbore C:/Documents and settings/Username/Application Data/Opera/Opera/wand.dat. A ešte tuším existuje pre Operu také
powertlačítko, ktoré ti po stlačení wandu ukáže (nezahviezdičkované) aké heslo odosielaš.

The terms LF, MF, and HF refer to low, medium, and high frequency, respectively. Clearly, when the names were assigned, nobody expected to go above 10 MHz, so the higher bands were later named the Very, Ultra, Super, Extremely, and Tremendously High Frequency bands. Beyond that there are no names, but Incredibly, Astonishingly, and Prodigiously high frequency (IHF, AHF, and PHF) would sound nice.
