[Inkscape-user] graphic tablet problem

I am having problems with my wacom intuos 3 tablet. It works on all the tools and when I go to add it, it appears to be there but I can't change any of the settings. It works in other programs like PSP ok and I have the latest driver installed.

I am using inkscape .46 and .47 and can't get it to work in either. But strangely (no idea why I tried this) the erasor seems to work ! No idea why. Can someone help me here please ?

cheers, Jo
