Three times this year I have had Macs with the following problem. I always have had the latest version of the OS. Suddenly, when I use the Shift key, I can't get one capital letter unless I use the Caps Lock key. First, on my QS DP 800, I had the problem with the B. I created a new user and no problem. Whatever application I was in, Shift b brought up GraphicConverter, but no Keyboard Shortcut had been created for this. Start from a different HD and no problem. I erased the HD and sold the computer. Next, my AlBook 12 did the same thing with the Shift k. I don't remember what application application came up when I did a Shift k, but if I wanted a capital k, I had to use the Caps Lock key. I had a cloned version of the HD so cloning it back solved the problem. Today, my G5 iMac started doing the same thing with Shift c. No matter what application, Shift c brought CopyPaste to the front. Again, the Caps Lock key is what I had to use if I wanted a capital C. I had a cloned version of this HD and I cloned it back so all is okay now. What could be causing this? I posted messages on Apple Discussions and the most reasonable response was that older versions of CopyPaste or Synergy could be the problem. I don't have Synergy and have always had the latest version of CopyPaste. I posted a message at CopyPaste about this today. If there's a preference for Keyboard Shortcuts, maybe trashing that would help, but I don't see one. Tom Miller
