Thank you for writing.
I confirm that issues exist in the latest official release Q1 2012 (2012.2 608). I am glad to inform you that we have already addressed them in our internal build and you can take advantage of this fix in the upcoming service pack, which will be available by the end of the month. I cannot give you temporary solution due to complexity of the issue.
I hope that you find this information useful.
