Hello all, First I would like to say that I have searched, but have not found an answer to this particular question. I recently picked up an Hp tc4200 tablet. It runs vista business for tablets. My pen came half smashed to bits, so I purchased another one online. The problem I am having is that after installing the driver from the hp website, the new pen works fine, but then after closing my computer or going into standby, and starting my computer back up, the pen will not work unless I reinstall and restart my computer again. Is their any perminant fix to my pen problem?
