oclHashcat v0.18 HD5970 not work

[xiaozhi]

we have tested the HD5970 a lot. there are no known problems. do you have tried running other opencl applications (just to make sure your driver installations and the card are working)?

thanks. the problem has been resolved...

but there's another question: i have two cards , but only one is working at the same time.

can the application using serval cards one time?
