When I go to inspector it used to open with a dark gray background and I could manipulate everything fine. Now most of it is light gray and I can't do anything in there. There is also a check box that says Show 0 hidden items in this breakpoint

Have I clicked something stupid here?

Thanks

I seem to remember that you are still using RSD2.5, and attached is a screenshot of how it looks like with the Inspector pane open.

I don't know what you may have done, but if you can't get it to work again (e.g. by closing and reopening the app), you have a good reason to upgrade to a newer version. I'd say that you can't expect any fixes for the old programme version any more.
