The SourceOffSite 4.0 Client comes with a new Diff/Merge utility from SourceGear. For new users, this is the default application for diffing and merging files.
For users who upgraded to 4.0 from 3.5, the upgrade does not change your previously configured applications for diff and merge. Therefore, to use the new SourceGear Diff/Merge utility, you need to go to the External Programs tab of the Options dialog in the SOS GUI Client. The name of the SourceGear Diff/Merge executable is "sgdm.exe" and it is located in your SOS Client installation folder.
