I have downloaded and installed the 30 day trial version of Vivik. BTW it also installs a speech engine which I am guessing is why the file was so large. I went into AHP and tried editing a module. I was able to type in any of the text boxes using Vivik. I then went to one of my rooms and double clicked on the name header of one of my modules. I was also able to type in there.
msmendel, you may want to check in your windows device manager (Start > control panel > system, hardware tab at top, device manager button) see if there are any yellow exclamations next to any devices. It sounds like there is possibly a driver conflict that may be giving you grief.
Dan L., a virtual keyboard is not a device that connects to the computer. It is a software based keyboard that runs on the machine and acts like a normal keyboard. People with disabilities like msmendel can control these with a mouse, joystick, track ball or other device to move the mouse and click on the virtual keys. Whatever is typed is entered into the system just as if it were typed on a physical keyboard.
