By default, in Visual Studio and in SQL Server Management Studio, Ctrl+Tab opens a navigation popup which lists all the open windows. The idea is that you can press Tab multiple times while keeping Ctrl pressed; as soon as you release Ctrl, the navigation popup disappears and the selected document is activated.
Unfortunately, as soon as you ever run Microsoft Narrator (text-to-speech reader), this behaviour changes. The popup no longer disappears when you release Ctrl; it waits until you press Enter to select a document. While I can appreciate this behaviour may be reasonable for blind people who are actually reliant on Narrator, I find it rather irritating that the behaviour has changed permanently and that the old behaviour doesn't return even if I stop using Narrator completely.
Is there any way to restore the old behaviour so that it doesn't wait for an extra Enter keypress anymore?
Be patient and it magically starts reverting to normal after not using Narrator or Speech Recognition for a month or so.
