I'm not sure this is the correct forum in do this in, but I have a problem with using the Wifi at my university and the multi-desktop feature of OS X Yosemite. When I log onto my university wifi it comes up with a Safari/Chrome pop-up window detailing my internet usage. Unfortunately, it doesn't take into account the multi-desktop feature of OS X Yosemite. The window is always on top of all the desktops - it sits in front of my Word document, my pdf document, my general web browsing etc. When I swipe between the desktops it just just comes along and gets in the way. There are no options on the window other than closing it. Unfortunately, if I close the window, it disables my connection. The problem is independent of which browser (Safari/Chrome) that is the default browser. Is there a way to disable the 'always on top' nature of this window?
