Just files a support request for this:
Phenomenon: Using open source WinMerge as File Comparison utility for Source Control does not show differences.
Running WinMerge by itself has no problems. *Reproduce Steps: Install WinMerge and specify it as the File Comparison Utility in the Source Control properties. Select Show Difference from the System Tree; nothing displays. Remarks: WinMerge is an MDI application and it appears it is not allowed to become visible? Or something.
Anyone have any experience with this? Or suggestions as to what might be wrong?
Regards,
Phil
