Every time I compile my beamer presentation, I get a list of 83 errors all of the form:

Undefined Control Sequence


at each \end{frame} line.

How do I fix this?

• Can you please add to your question a minimal example code illustrating the undesired bahaviour? Apr 14 '11 at 4:06
• This sounds like a 'passing' issue with particular versions of hyperref Could you add \listfiles to a minimal example and add the resulting file list to your question? Apr 14 '11 at 6:14
• You must update hyperref to version v6.82f. or later. (The bug is in 6.82e). If there is no update available yet, you can try to add \makeatletter\def\Hy@xspace@end{}\makeatother after loading beamer as a temporarly workaround. Apr 14 '11 at 6:49
