SP2010 Bug? Cannot change List View in Ribbon. List view drop down not responding?

Question

In all of my Libraries I have 3-5 views (standard and custom), I cannot select them from the Ribbon thought, the drop down button does not respond when clicked (nothing happens):
When going with the mouse over the drop down button it shows "javascript:;" in the IE status bar.
The only way to change the view, for the moment, is to do it via Library Settings and set the selected view as default.
Is this a know issue? Is there any settings that I`m missing?
Many thanks!
Cheers,
