Worksession + blocks issue

I am having an issue in using both work sessions and embedded Blocks together. If I have the same block name referenced in different files worksessioned together they will all disappear except for the current file open in the worksession. This is incredibly problematic for me. Perhaps I am using worksessions in the wrong way?

Has anybody encountered this problem?

Hi idhelp- I responded from tech support on this earlier today- was my description there a reasonable test for this problem (I could not reproduce, but I suspect there are plenty of possible differences in what I am doing compared to you.)
