Elements 9's PhotoMerge crashes with Mac OS 10.9.2

Question

In attempting to use any sort of PhotoMerge functions in PS Elements 9 on my Mac results in the program immediately crashing, regardless of what I attempt to do. I have successfully used PhotoMerge, but never had this happen before -- until now, after attempting to use it with Mac OS 10.9.2. All my software is up to date, and I have tried every variation on a theme to get this to work, but to no avail. It fails and crashes repeatedly and instanteously, the second I click on, and attempt to move, a photo from the project bin to the "Final" window for use as the base image. Has anyone else had this problem? It is infuriating.

Barbara:
     No, I haven't dropped off the face of the earth; it just seems that way.  Sorry about that. I'm afraid that actual work came up, and I have been sidetracked with it until this evening.
     Anyway, I wasn't sure how to go about creating a new admin user, as per your suggestion, so I went back into PSE to see if somehow something had miraculously changed. And, lo and behold, it had: This time PSE allowed me to move a photo to the "Final" window to use as a base image without a hitch. But only once. The next time I tried it, it failed again. But being thick-headed, I tried again once more and it worked. And it continues to work -- knock wood. I cannot explain what happened or why it changed, but that's where it stands at the moment.
     Thank you for your help and advice. I might have to seek it again if this quirk reappears. Thanks very much again.
