Problems with Fn + Space bar during dual display mode.

[tockki]

When I have my setup with dual display, there is a function where you can directly put the window you are using onto the secondary display without dragging the window to the secondary display - "Fn + Space bar". I have used this function frequently during presentations on my other T60 but with the T60 setup at home, an error occurs and the program crashes and shuts down. I have been trying to find the program on the download site but couldn't find it. I was wondering whether anyone out there knows what program/driver to download to make this work again. Thanks.
