Doesn’t seem to work well

I can get things loaded and then BAM, I get his blank page. the sidebar buttons will not take me back or to another area. Keyboard shortcuts don’t function then either. There is no back button . It looks perfect when first opened, but then it falls apart when trying to do anything other than scrolling through the group you are in at the moment. The idea seems pretty good, but it just doesn’t work more than starting up. I will add that if I quit snad start it back up I at least see pictures. But again, moving to an image pretty much causes every button to fail afterwards.
