works with threads, not with processes

[jfelchner]

Yeah a process is a completely different process so you'd need a progressbar instance defined for each process. However even then, you can only show one progressbar on the screen at a time. I think what you're wanting is to have one progressbar that is able to be incremented in each process and that's not possible.

Please let me know if I'm misunderstanding what you're doing but I'm going to close this
