I have the problem that shortly after accessing Webfig with Safari, the interface becomes somewhat unresponsive. With that I mean that when I click on some item on the menu bar on the left, the URL bar is updated, but not the web page content according to the selection. However, values in the content keep updating. For example, if I am viewing the "Interfaces" page, the interface statistics keep updating, but if I click on, e.g., "Switch", the main page continues showing the interface page with statistics being updated, and I don't get the "Switch" view.
I can go to the desired page (e.g. "Switch") by using the browser's "Reload" function, but in that case I have to authenticate again. Doing so for each page on webfig is quite annoying.
The problem does not appear if I use Firefox as a browser.
