using tablet with Intellicad

I'm trying to setup a tablet to work with Intellicad 2.2.0010. The tablet is Calcomp Drawing Board 2 connected to a Windows 2000 Pro computer using latest Calcomp wintab drivers.When I go into tablet-configure and get to the prompt asking to select upper left corner of the area 1 it just stops there and I can click anywhere on the tablet, but it just sits there forever. I have to press ESC several times to cancel TABLET command. Sometimes after that tablet stops working completely (I mean does not even work as a regular mouse). This setup works on AutoCAD 13 that is installed on this computer just fine.
