Hi, thanks for the response - it is displaying Vista view option 'Medium icons'; I've tried changing this to small icons. Hhowever, I have just noted that it, when I had a prob. just now with it not responding when I Alt-tabbed from a game, it was showing itself with a Word document icon, also in Task Manager when I went to kill it... so it does look like there may be some sort of corruption issue? On re-opening it, it showed the Games icon (the cup) again. Note, a number of the games I play are old silly things, with low screen resolution, so I guess the desktop etc has to completely refresh when I switch like that. Maybe that is a prob for it.
I have 3Gb RAM and I don't have any particular problems with boot up time, it is slowed down by the fact that MSN starts up automatically, but otherwise it's OK (oh, except I have Speech Recognition switched on and can't find out how to turn it off again, that is a recent prob. when I thought I'd give it a try, any hints how to turn off gratefully received!). I recently ran TuneUp Doctor, that helped me sort out a number of things, and I review all the running processes at frequent intervals, and try to ensure I don't have any virus/spyware issues, or any unwanted services... except this Speech Recognition thingy of course :)
