First can I say that I'm not computer literate, I just use a PC . . haven't got a clue what goes on under the bonnet, this is just a simple observation. Don't know if anybody else has had the same problem as me? Recently downloaded IE8, but then uninstalled when I read that there were security issues, and reverted back to IE7 as the blurb said . . . only to find I'd lost the ability to lay down my cursor in any relevant box on screen. Couldn't enter script anywhere, but the mouse still worked as far as other tasks were concerned. The cure? I re-installed IE8 and all OK again, as this text proves. Not a happy bunny though, as I found IE7 easier to use than IE8.
