After selecting multiple files (unstaged, staged, history...) and invoking External Diff (CTRL+D) with Beyond Compare configured as a Diff and Merge tool, only the first tab in BC contains the previous file whereas other tabs point to non-existing file. Any additional diffs do not work either unless BC is closed.
1. Selecting three changed files and hitting CTRL+D

2. First tab opens properly 
3. Second and further tabs miss their left files

It worked in previous versions and used this functional prior every single commit so it is pretty much vital for me. Can anybody reproduce this? Any other ideas?
Thank you
