• _daz Infopath and WWF

  Hi, I was wondering if/how WWF can be used to manage the state of Infopath forms so that certain elements of the form can be hidden/shown depending on the state. From the tutorials that I've looked at, most of them use a Windows form to input the data rather than an Infopath form. I appreciate the help.

• svn Killing Fast User Switching in Vista32

  I have security applications that will not function using FUS. In XP there was an Option in the control panel to kill FUS. How do you kill it in Vista32 I'm not sure there is a way to turn off FUS in Vista. I'm sure someone more familiar could verify that. That being said, turning off FUS might not fix your problem.
