The addons for Shadow4 skin 1.6:

www.rainlendar.net/download/1.6/Shadow4-Languages.r2skin-addon

Changes:
o Fixed text wrapping when the area gets really small.
o Column order in the manager can be changed by dragging (only supported on Windows though).
o It's now possible to define any file for the alarm. All non-audio files are executed instead of played back.
o Changed the way Google alarms are defined. You now have option to always use alert, the Google's methods or the default Google notifications.
o Added advanced setting to delay the network access on startup.
o Category filters didn't work for translated category names. Fixed.
o Retry if proxy fails setting didn't work with RTM. Fixed.
o Added grid calendar for the Chromophore skin.
o Added navigation arrows to the day and week views in the Shadow4 skin.
o The first uncompleted task is now shown from RTM (previously it was the last one).
o Changes to the window positioning on Mac. The dialogs stay now always on top since previously they could open behind other windows.

Doesn't start up on osx (10.6.2). On open nothing happens...
here is the log:

On Snow Leopard this version will NOT start. For some reason, even the crash reporter does not start. The rainlendar2.log was not even started. I'll try tomorrow again, when I restart my imac. Reverting to the previous beta works fine.

Edit: Larzon beat me to it by a minute or so
Same console output here as Larzon has

It seems that the two "r2skin-addon"-files are only installable when rainlendar is closed. (Win7-64bit). Otherwise I get this error: "DDE execute request failed: a transaction failed." (I had the previous beta installed if this is of concern).

Thank you for the new beta!

The Mac version seems to read the libraries from incorrect place. I'll fix that tomorrow.

On WinXP SP3, too.
