A student brought her MacBook to class and asked me to troubleshoot her new install of CS5. It would lock up when starting up, with the SBBD (Spinning Beach Ball of Death). I tried resetting preferences, to no avail. She had no third-party plug-ins, no font auto-activation — none of the common culprits. It was a clean install.
Poking through the Adobe forums, though, I came across a thread on the same problem. One poster found that deleting the SING.InDesignPlugin cured the problem.
Sure enough, that did the trick! She is now SBBD-free, and InDesign launches and runs with no problem. I didn’t have this problem on either my desktop Mac or my laptop, so I don’t know why it affects some folks but not others. But I’m passing it on in hopes it will help others.
The plug-in is here:
