In Manage Jenkins > Plugin Center, if I click 'Check Now' I am taken to the 'Installing Plugins/Upgrades' page. I don't see the relevance of that page to this function. I just want to stay on the page that lists the available updates.

Also, when I return to Manage Jenkins > Plugin Center the update time is still shown as a day or so ago. So the 'Check now' seems to have had no effect.

'Use browser for metadata download' is unchecked.
