Join Relationship Functionality Limited after IE Update

[egates17]

We no longer are able to set cardinality for joins via Report Studio.  All joins are showing up as Join Relationships (Collection) for existing reports and new reports.  The UI only shows the Join Expression box.  We did not actively change any settings; this popped up after weekend IE update. Coincidentally this is now the default RS join behavior in our DEV, QA and PROD environments.  Any ideas?

Update:  This works fine in Mozilla!  Apparently a result of an IE update ?

Very hard to comment on this as you do not specify IE and Cognos versions. We had lots of issues with IE8, especially with Cognos versions prior to 8.4.1. What is your setup?

8.4.1 running on IE7.

Update: We found that the culprit was hotfix KB2416400.  Once we removed that the report studio UI for joins was back to normal.  Thanks
