There's a small error in the sidebar.xml file:
appearance layer="10" element="bitmap.today.%Shape%" align="CENTER"

it should be:
appearance layer="10" element="bitmap.today.%Today_shape%" align="CENTER"

And btw, "Vejr" is "Weather", "Nedtælling" is "Countdown" and "Billeder" is "Photos" in danish.

Thanks, I'll fix that.

Windows XP SP2
Rainlendar 2.3 build 61

When I turn on any of skins Vitrum08.1.5 log file give me many times of warning:

19:47:23: [0:00:22.078] WARNING: The item "" has invalid x2 ().
19:47:23: [0:00:22.078] WARNING: The item "" has invalid y2 ().

Vitrum08 repeates this message 3 times, Vitrum08w - 60 times (!).
What is wrong for this beta?

Those warnings come from the time items which don't define the width and height. The warning is unnecessary so I'll remove it from the next build.

Rainlendar doesn't start on Windows 2000. It requires faultrep.dll which is available only on Windows XP and later.
