Hi,
I'm the senior test lead at Microsoft responsible for the Windows Imaging Component. This issue was brought to my attention just overnight, so I figured that I'd reply. We're certainly interested in these types of issues, so would you mind emailing me the original file, the files after it was saved in Lightroom, and the file after it was saved in ACDSee? Please email me from my blog at
http://blogs.msdn.com/rwlodarc or through the forum. (I'd rather not post my email to prevent spam.)
Thanks,
Robert.
