Upon upgrading to 1.5.10 (1616) my command-R short-cut is broken again.  Yes, I know, I know.  It is marked "changed" in the release notes, the interactive dylib is nowhere on my machine and the interactive disabled shell variable is set to "true".  It worked properly before I upgraded and now it is broken again. 

I've read the forum threads and as near as I can tell, what is happening should be impossible.  Anyone have any suggestions? 

Thank you for your help,
Peter
