So I took my computer apart and fiddled with some bits and now not only is the keyboard still wonky (it looked like it was working properly for about 5 minutes) but the mouse has stopped working too. Before I took it apart I couldn't even get my spare keyboard to work. The kids had unplugged the computer thereby running down the battery and causing it to shut down. I couldn't even get it to boot up. Add to that the fact that Firefox is on the blink and I am seriously put out. Thankfully hubby's penchant for hoarding computer parts means that I have a spare mouse to work with.
