[Pythonmac-SIG] appscript with todos in iCal seams very slow

[Marcin Komorowski]

Thanks Has, this definitely did the trick.

I guess when I get to updating individual values in selected todos  
records, I will have to use a relatively slow request-per-update  
method.  Is there a trick to update a field of a todo with a given  
uid in a single request?

Thanks,
Marcin
