Q. I am running Vista Home Premium on a new Dell laptop and have recently started getting the following error message: 'wsst_engine mfc Application has stopped working'. I can get rid of the message by hitting the Esc key and it does not appear to affect any programs but it keeps on popping up several times in a working session. I have looked on the Microsoft Knowledgebase but a search yields no results. Do you have any ideas as to what is going on, if it is important or not and how to stop the message appearing?

A. This file belongs to a screensaver program developed by a company called West, which is also marketed under the name Auralis and include such visual delights as Bikini Girls, Snakes, BackStreet Boys and World Wrestling Federation Stars. Anyway, if you have installed a screensaver of this type on your laptop, get rid of it and the problem will go away. It should appear on the list in Programs and Features in Control Panel. .
