[Leica] Lightroom Problems

[abridge at mac.com (Adam Bridge)]

This is very troubling, Gerry.

I?ve played a bit this afternoon to see if I could duplicate your results. 
Running Lightroom 2015 CC on MacOS Yosemite 10.10.3 I could not reproduce 
this. 

I think you should submit a bug report to Adobe.

For my own peace of mind: what is your system configuration and when did you 
do the renaming operation? I?m assuming you used Lightroom to do the rename. 
I?d certainly have expected the side-car files to be renamed at the same 
time.
