Hi Sue Check to see if there are any prompts or windows that may have opened in the background which are awaiting action.
Press Alt + Page Down (not the arrow pointing down) together on your keyboard if that doesn't work try Alt + Page Up. One of these sequences should allow any other Hosted windows to appear on the forefront.
If the above does not work, please log out of Hosted (File > Exit). Click on the Control Panel > Log off remote sessions > ensure your session is logged off. Log back in and try again.
