A few bugs

I'm running into a few bugs atm:

• Expanding / collapsing items won't work with a single click. But it still works if I double-click.
• Pages won't remember whether nodes are expanded or collapsed after being refreshed.
• If I'm zoomed in on an item and I refresh the page, the page will never finish loading.
• I'm constantly getting a message to "reload to the the latest version", even after reloading the page.

Hope this helps.
