WinMerge starts fine, I just can't get the command line arguments to pass to the Windows exe. Ok. From what you said I can recommend the following, which must be run from terminal (Applications folder then Utilities): [code] cd /Applications/WinXP/drive_c/Program\ Files/WinMerge wine WinMergeU.exe "Z:\Users\usera Z:\Users\userb" [/code] Is this how the program is run under Windows? I'm not assuming that parameters to this program are passed like this. James McKenzie
