Is one of the two processes the GUI version and one the console version? The instructions warn against that.
Or do you have two copies of the console version running in different directories?
If it's the latter case, I'd just let it run until it finshed a work unit and then trash the one that finished first.
only console no GUI
I have deleted everything I could find and started from scratch several times - it would not let go .. maybe this last time I did it right cause it's back to processing one WU @ 97%
Thanks
