Hello and thanks for your reply.
I already installed the 1.1.4 version. But I have weather display and wswin32 which are working at same time. WD is working ok but I have problems with wswin32 which is always loosing the port. It seems to be not adapted to work with an USB port.
I think that I will have to change this usb port for a serial one.
Cheers
Isabelle
