Hi, Thanks for the reply but your initial good advice does not appear to work. I have not used Autosizer as yet but am a bit puzzled as to why my system has gone like this. Is this normal and what could have caused this? I have had my PC for six months and used it normally each time until yesterday. I did nothing nothing out of the ordinary (a creature of habit!) and have never had this problem before. Could a virus be in my system? I have Windows XP and when going into properties nothing appears as 'run' in the choices. I have also tried your other advice and that does not work either. Is this a common problem? Thanks again for your prompt advice Mike P
