VSTools for Unity Error List displaying "0 of 19 Errors"

The warning/error/messages window that is added to Visual Studio has never shown me a message for more than 1 second before clearing the window. There doesn’t appear to be anything I can do to actually see the messages it claims to want to show me.

That wouldn’t be too annoying if I could just close the window and forget about it. But, it likes to re-add itself to my layout and bring itself to the front over other tabs, such as the debugger call stack…

Aaand, right after complaining I figure out that the filter was set to “Current Project” when it should have been “Entire Solution”. Now I can see the errors.
