In case anyone else encounters the same issue, I will post here the same information I gave you in your other thread:
We can confirm that this is a bug but unfortunately we aren't aware of any workarounds. However we have logged it in our PITS
(the item is logged both for Silverlight and WPF, even though the Product states only Silverlight) and we will do our best to fix it for the next minor release - Q1 2012 SP1.
