Hello,
I just bought the library and when I try the demo application in windows Vista (English) business, when trying to add any task I get a message saying "The task XML contains a value which is incorrectly formatted or out of range.". Is there any fix to that? What could be causing the problem? The same exe works fine on W2K or XP.
Unfortunately, we're unable to reproduce this. Could you please try to change some creating task item properties in Demo application and check if the error changes or goes away?
