A couple of days ago I noticed that the click-to-copy-to-clipboard share links at Skitch’s site stopped working. I thought it was because of MultiClutch, a program that gives you multi-touch inputs to all Cocoa programs, I wanted to be able to use 3-finger swipes left and right to navigate back and forward in Firefox. I uninstalled that and the input manager it came with and the click-to-copy links still didn’t work. So I think about it more, and since I know how these click-to-copy links work pretty well, I know that most of them depends on Flash to copy to clipboard, and then it occurred to me that I had upgraded Flash to version 10.
I then downgraded it back to version 9 and the click-to-copy links now all work again. 🙂 So if you’re googling the same problem, check your Flash version (about:plugins), and see if it’s version 10, if so, downgrade it back to 9.
