False Power PC no longer supported error
Recently my MacPro has been giving multiple errors that I can't open a particular application because PowerPC application are no longer supported. It references an application that I don't have on my computer and I'm not trying to open. I keeps listing the error over and over. Last night it listed it 88 times before I woke up this morning. They list one on top of the other running down from the middle of the screen to the right lower corner and then pile up there. I don't know what to do other than erase the drive and reformat and I really don't want to do that. I'm attaching a screenshot.
This shot shows 8 repeats in about 4 hours one day last week. This started about 3 months after I installed Lion, and I haven't installed anything else since I upgraded to Lion.
Any help will be appreciated. I am really tired of deleting these error messages. Thanks very much.
