[Bug, TF2, 8860] Crash When Aligning After Switching Views

[Kestrelguy]

I was trying to align a prop to the nearest floor. for some reason, I thought Ctrl+N was the shortcut for that. it wasn't, and it opened up a new file. I closed that file and was brought back to the original, with a black 3D view to greet me. this is, in my experience, pretty normal when switching between windows, so I just navigated to the actual align to floor tool and clicked it, expecting the 3D view to return. instead, H++ crashed. switchcrash.zip
