where you write the messages, below there should be a couple of tabs. One if for normal writting and the other for handwritting. (I think that you also need Windows 2000/XP/2003 and you have to install the ink redistributables too (for example from
http://www.xs4all.nl/~immi/fanatic/ (one of the first links found in google, dunno if it works))).
edit: oww
too late
