By CM 7.1 - I am going to assume that you mean IBM Rational CM Synergy 7.1 (please confirm)
You can use Beyond Compare by following the instructions in this technote
which says, **Set-up the Classic client to use BeyondCompare, by specifying in your %USERPROFILE%\ccm.ini file:
merge_cmd = "C:\PROGRA~1\BEYOND~1\BC2.exe" %file1 %file2 /savetarget=%outfile
Then once you select Interactive Merge from within Synergy, you merely have to save one side or the other, or "Save as" and Synergy will create the next version.**
Give this a try and let us know if this works. Oh and scooters has a nice little technote about using BeyondCompare with just about any version control tool known to man.
Unfortunately, as the IBM technote indicates the instructions in the Scooters technote do not always work.
