In this week's programme Adam Walton discusses remote access for home computer users. There's advice for those filling in their tax returns online. PC Doctor Simon Zerafa answers two more listeners' questions and we hear how Hollywood gets technology wrong.

One of several technologies predicted to become the next "must-have" is the ability to access our home and work PCs remotely. But is the technology reliable and secure? This need to keep in touch with our home computers is becoming increasingly part of our day-to-day lives and businesses, and access to information wherever it is stored is going to become more important. Chris Long, a reporter with BBC Click discusses how remote access works.

Christmas is but a distant memory, the decorations are down, and there is a dark shadow hanging over many thousands of us because it's that time of year when the deadline is looming for self assessment tax returns to be filled in.

In Hollywood movies, everytime soemone comes across a computer - no matter where there are in time and space - they seem to quickly grasp the interface - are able to guess passwords and, generally, save the day at the push of a button. This skewed vision of technology in the movies inspired usability expert Jakob Neilsen to create a light-hearted hit list of techno-gaffes. Stuart Miles of Pocket Lint discusses this skewed vision of technology with

Our regular PC Doctor Simon Zerafa is back in the Haverfordwest studio and has two listeners' questions to answer.
Question One is from Dave Williams who says: I'm unable to install google earth on my PC. I am runing windows XP.The install wizard seems not to run. I suspect it's a configuration problem. Could you advise me what to check please. My PC is a 3 year old Compaq.
Simon says: Google Earth seems good normally, so double check by downloading it again to make sure the installer is intact. It uses a piece of software called Install Shield. Occasionally this can go wrong, so he could try navigating via My Computer to C:Program File>Common Files. In that folder you will find a folder called Install Shield. If you temporarily rename or move that folder and then try running Google Earth installer again it may install correctly. If not, put the Install Shield folder back where it was before. Otherwise it could be a problem with your Windows set up. If you have no joy, get back in touch with us.

Question Two is from Bryan Jones in Penmaenmawr - I have been using and EasyDisk 512MB memory stick on my IT couse at Coleg Menai and in the local library with no problems. At home, I have an old PC, on Windows 98, not yet on the net, but this does not even show the disk on Windows Explorer or My Computer. The Floppy Disk input/output works OK. Is there a simple answer to this? If I need to, I can use the library computer to find and download a suitable driver onto a floppy, but I have to know what to look for, hope you can help me with this one, thanks. Bryan
Simon says: Most USB flash drives work out of the box with no software drivers for Windows XP, Me or 2000, but for Windows 98 it requires a driver. For EasyDisk, go to their website and select the required driver based on the model number of the USB drive you have.
