I just purchased a Calcomp 9×6 tablet and pressure sensitive pen. I have tried to use it with Ani Pro but I can only get the tablet to work when I use it as a mouse. I can't seem to use the absolute mode. I have used the summa config on the tablet and set Ani Pro to use the summa config under the extra menu, but the cursor does not respond. Does anyone out there have some ideas? Thanx in advance, Paul Frey
