Hi Joe,
Can you let me know what browser you are using? I have noticed a similar scenario, but only while stories are still loading into the story list grid, something which is potentially slowed by some interesting performance issues that occur within Firefox and Chrome (but not IE). So for example, in the scenario I am aware of, if 500 stories are loading they will load in chunks of about 30 stories. As the 'chunks' come in and are being renedered, my UI locks a bit and my Persona Catalog button (along with others in the UI) becomes unusable. However if I wait until all the stories are loaded, the buttons all work as expected.
Could the above perhaps be the symptoms you are describing, or do you feel your issue is something else?
Regards,
