beamerdefaultoverlayspecification breaks references to bibliography
Hi I just noticed that my citations were all wrong - all had the same value. After some desperate research and some trials I get the impression that the problem is somehow related to beamerdefaultoverlayspecification. I generated the sample document where the problem shows up.
Please notice the duplicated reference to BM03 - which gets corrected upon deactivation of beamerdefaultoverlayspecification.
