G600 - just checking - did you delete the registry key and try again ? It's working just perfectly for me .

I didn't delete the registry key.
With the AltLogo.png in C:\Documents and Settings/Username/Application Data/Marine Aquarium 3 the L key works with 8g when executing from desktop. At first it didn't work when used as a screensaver till I saw that MA3Playlist is also in the C:\Windows\System32 folder so I placed AltLogo.png there too and then the L key was functional in screensaver mode.
