I have a big problem with my QS220.

Ocasionally, its Vutek User Interface freezes, and there's pretty much nothing I can do about it.

I have tried "killall java" commands, and restarts of the VuWare afterwards; I have tried restarting the machine...

After a bunch of restarts, it responds and works normally, but this means a lot... a LOT of restarts.

Any ideeas?

P.S. I have reinstalled the Linux on the machine a while ago, the problem did not dissapeared.
