My understanding is that the svn library does the merge... if it detects a conflict it creates two files... one with your file, one with the repository file and then the merged file with the conflicts marked. It passes these three files to Beyond Compare.. you use beyond compare to resolve the confluct. Once you have don't that you have to tell svn the conflict is resolved... how would it know otherwise?
This is all explained in chapter 4 section 6 of the TSVN doc. I quote a relevant portion here:
"Afterwards execute the command TortoiseSVN → Resolved and commit your modifications to the repository. Please note that the Resolve command does not really resolve the conflict. It just removes the filename.ext.mine and filename.ext.r* files, to allow you to commit your changes."
I think when using TortoiseMerge it has a button to "Save and Mark as Resolved" all in one swoop... which you don't have in Beyond Compare.
