Previously, when I used Leopard on my iMac, I had assigned F17 as my shortcut for "show spotlight window". Since upgrading to Snow Leopard, whenever I hit F17 for "show spotlight window" I only receiving an error 'beep' I've tried reassigning it to a different key or combination of keys and it still doesn't work. If I assign a different keyboard shortcut to F17, it works no problem, so the problem is with the "show spotlight window" and not the key I've assigned to it. As well, I also upgraded my MacBook to Snow Leopard as well. The key I had assigned for it to open "show spotlight window" (Fn F2) works the same as ever. I tried comparing all of the keyboard shortcuts between the two computers and making sure they work. Everything works fine except for the "show spotlight window" on the iMac. There is nothing else assigned to that key so I know that that's not the problem. I've searched the Internet to see if others have had a similar problem but I seem to be along on this one. Any suggestions would be greatly appreciated.
