Thank you for the replies, more food for thought.

I fear that I may not have stated the problem clearly enough. As I see it, the 
problem is in the original code that Sean kindly sent me. I wanted to know if 
there is a typo in this line:

> connect( m_workerThread->poller(), SIGNAL( value( int ) ),
>          this, SLOT( processValue( int ) ) );

There isn't a poller() function and if I create one then this is the result:

"invalid use of void expression"

I've been working on this application for a little over ten years, on and off, 
and it has grown somewhat during that time. I have added the most time-
intensive code into the function DevicePoller::poll() which still works but it 
blocks the GUI. Writing to and reading from the hardware is not the problem, 
as far as I can tell, because it all works correctly.

I'm happy to supply more code but I think the problem is in the connect line 
above.
