I'm trying to start explorer.exe with command line arguments from OSX terminal's command line. I can get it to open explorer.exe but it drops the arguments. For example: open explorer.exe --args C:\ This opens explorer but it doesn't start at C:\. I know a simple argument to explorer should work because if I go into the Windows guest VM and open up the command line (cmd.exe), I can type "explorer c:\" and it opens a new explorer window viewing the C:\ folder. I also created a simple batch file to see if argument passing would work and it didn't seem to. Is there another method to pass arguments via the 'open' command in OSX for guest OS executables? The reason I'm asking to do this is because my end goal is to create a url handler where Livemeeting links viewed in Mail can be clicked on to fire up livemeeting under the windows guest. Currently I'm just cutting/pasting the link address between OSX and Windows Guest. If anyone has other suggestions on how to accomplish this I'd love to hear them. Thanks.
