The only think I was using FastStone for was as an image browser and 
would never consider it as an editor with PhotoShop just a click away. 
I have used BreezeBrowser for at least 7 years and well prefer it to 
Bridge.  Therefore my strong disappointment that my current version is 
unable to do a simple slideshow from E-M5 embedded JPEGs.  I really 
don't care about precision of color results because all I'm looking for 
is a quick view of the camera's rendition of "as shot".  I use that view 
to decide what I'm going to keep or scrap.  All of the final photos will 
have been converted to my own preferences from the raw files.  The 
additional points about inability to extract JPEGs or convert ORF files 
is just a disappointment that the product hasn't maintained functional 
compatibility with Canon/Nikon raw files that has always been there.
