I found a rather crude but reasonably effective way to do this :
Download "trayman" from this link :
http://www.programurl.com/trayman.htmStart the application and add the winmx.exe file from your winmx folder into the application.
Then click ok
the winmx icon will now appear in your tray and will work with a single click.
I'll try to find a better program, but as of now this seems rather effective.
The options available on right clicking the normal winmx icon in the tray are unavailable.
But can be accessed by right clicking the winmx window in the taskbar, when the window is open...
Cheers
