up/down arrows in search & text field not working
Bit of an odd one this (and probably one with a simple solution). I've just moved from a rather aged PowerMac G5 to a nice new Mac Pro. This is great. However, when I use safari, the up/down arrows don't work within the search box. What I mean by this is; let's say I've searched something and the curser is at the end of the search box text, if I then want to go to start of the search text (say to change it) I'd normally press the up arrow. This would then take me straight to the start (shift&up will select all the text). This is obviously quicker than repeatedly pressing the left arrow. But it's not working! Any thoughts?
All software updates are loaded. I'm using safari v4.0.2. It doesn't appear to be a problem in other programmes (like text edit) but I've not really checked everything else exhaustively.
