Beyond Compare Merge Won't Complete

[Patrick Duffy]

I am using Beyond Compare 4 as an external merge tool using the default settings in Sourcetree 3.4.2

Diff Command: C:\Program Files\Beyond Compare 4\BComp.exe

Arguments: \"$LOCAL\" \"$REMOTE\"

Merge Command: C:\Program Files\Beyond Compare 4\BComp.exe

Arguments: \"$LOCAL\" \"$REMOTE\" \"$BASE\" \"$MERGED\"

When I launch the external merge tool, Beyond Compare launches and I am able to merge the files and save the LOCAL and REMOTE copies. However, when I exit Beyond Compare, Sourcetree still has the "Visual Merge In Progress" window open, waiting for the merge tool to be closed. Is there a configuration or step that I am missing?
