Symptoms

Virtuoso is running (shows in the system tray, next to the clock), but when the user holds Ctrl down and slides the mouse to the side of the screen, Virtuoso doesn't appear.

Discussion

We have seen a number of cases where some other application prevents the Virtuoso toolbar from being the top most window on your Windows desktop.  This means that when the user places the mouse on the side of the screen, the Virtuoso toolbar does not receive the notification telling it to show itself.

It is also possible that the user has placed the Virtuoso toolbar on the other side of the screen, or is not holding the correct keyboard keys down while sliding the mouse.  These settings can be easily checked by right clicking on the Virtuoso system tray icon, Settings.

Resolution

If the Virtuoso toolbar is no longer the topmost window, right clicking on the Virtuoso system tray icon (next to the clock) is sufficient to bring it to the front.  After right clicking, the user can now slide the mouse to the side of the screen and the Virtuoso toolbar should appear.
