Phew !!!!! thanks guys, I think I'd better admit defeat at the hands of technology ;-)
Weeksy: in the bottom right I have several icons, from the clock leftwards Norton Antivirus, CD creation Wizard, SB AudioPCI 128D Mixer, Task Scheduler.
Using Windows 98 OK I'm still in the dark ages but up to now it's been OK, I don't use the PC for anything fancy, bit of word processing, emailing, surfing.
I'll have a look at the other sites you mentioned for advice.
Once again thanks for all the advice.
