o Added option for xml skins to execute the given function on startup/refresh.
o Second parameter for a lua function wasn't parsed correctly. Fixed.
o Improvementes in the scripting support: added possibility to download files and implemented attributes for all items.
o Images can have uniform scaling.
o Added possibility to hide canceled tasks from the todo list.
o Hiding completed/canceled tasks hides them in the calendar too.
o Keyboard navigation changed the months twice in Mac. Fixed.
o Added option to (not to) use window names in the calendar and other windows.
o Newlines in the text caused drawing problems if there was room only for a single line. Fixed.
o Help didn't work in the Mac version. Fixed.
o Changed the way dates are calculated in the calendar. This hopefully fixes the problem with duplicate dates.
o Moving all windows at once to the active skin didn't work in Mac. Fixed.
o Single instance check doesn't prevent the application from starting anymore.

There is also an addon package for the Shadow4 skin for those who are interested. You need this build (or never) to use it. It can be downloaded from here: www.rainlendar.net/cms/index.php?option=com_kunena&Itemid=36&func=view&catid=6&id=6164#6164

When I upgraded to build 56 I am not able to dismiss daily alarm pop ups. This happens when I first load Rainlendar, and only stops if I refresh.

I downgraded to build 55 and behaviour went back to normal.

What about showing MS outlook tasks in calendar? Is there a chance to have it in next build?

I noticed the problem with the alarms too. I'll fix that in the next version.

I'm doing some work in the Outlook plugin at the moment so if I have time I'll add the option to put the tasks to the calendar too.

I'd love to have iCal & Adressbook integration - that would be awesome!!!
And a option for stay on dektop -> available on all spaces and no dock icon. I hope this features will be in next versions.
But the beta works great so far, thanks for that!
