Bug with External Diff on Vista

I'm using -
    TortoiseSVN 1.4.3, Build 8645 - 32 Bit , 2007/02/04 09:40:57

I'm running on Windows Vista Home Premium 32bit.

I installed the Perforce Diff and Merge tools and setup the command to execture the diff as -
    "C:\Program Files\Perforce\p4diff.exe" "%base" "?%mine"

The file I'm diff-ing is called main.cpp in the directory - "C:\IrrSpintz\trunk\original examples\IrrTerrainRendering"

When I right click and and select Diff, the dialog comes up for the Perforce Diff tool and File 2 is displayed as -
    ?C:\IrrSpintz\trunk\original

Don't know where the question mark comes from and it's getting screwed up on the space between 'original' and 'examples' in the path. I have %base and %mine in quotes, same as I did on Windows XP where everything worked.

I'm not on the mailing list, so if I could be CC'd to my personal email on responses to this please.

Thanks
