minimise to taskbar, not tray

Hi - thanks for a lovely programme...

I have a question, and please excuse me if I'm being thick - is it possible to stop tabbyfile using the tray altogether?  I would prefer it to act like a normal explorer window, i.e minimise to the taskbar; is there a way to do this? 

I thought the 'show taskbar button' switch might do it, but it doesn't seem to work as advertised.

Thanks again...
