Since upgrading to v9, over the top of a v8 install, I am having trouble using Ctrl+T / GoTo Everything in VS 2013 Premium (all updates applied).
The dialog appears and I can type but no filtering occurs. Recent files are displayed, as though I was yet to type anything.
Restarting Visual Studio seems to fix it. I haven't yet found what breaks it (builds, new files, etc) but once broken it stays broken until the restart.
